Laser hair removal

Introduction to laser hair removal

Laser hair removal is a technology-driven aesthetic treatment that aims to reduce unwanted body hair safely and effectively. In the UK, it has gained significant traction among individuals looking for a longer-lasting alternative to traditional methods such as shaving, waxing or threading. By harnessing the power of specific light wavelengths, laser treatments target the root of the hair follicle and interrupt the growth cycle. As demand grows, innovations have made laser hair removal more accessible and less invasive, giving many people renewed confidence in their appearance.

Laser hair removal works by selectively targeting the pigment (melanin) within the hair follicle. When the laser beam is directed at an area of skin, it penetrates the outer layers to interact with melanin. Heat builds up within the follicle, impairing its ability to regrow hair. Over several sessions—usually spaced weeks apart—hair becomes noticeably thinner and sparser. This guide will explore everything UK consumers need to know about laser hair removal, from how the technology functions to its potential side effects, costs and future trends.

Key reasons for its popularity in the UK

• Long-term reduction in hair growth compared to other methods.

• Time-saving benefits, as fewer repetitive hair removal sessions are required.

• Reduced irritation, important for those prone to rashes and ingrown hairs.

• Increasing affordability and availability of professional clinics.

While laser hair removal is widely regarded as safe, it’s crucial for prospective clients to understand the procedure in detail before proceeding. As with any cosmetic treatment, results can vary based on factors like skin tone, hair colour and overall health. In some instances, alternative methods or advanced laser technologies may better suit a person’s unique needs.

Potential barriers

• Skin sensitivity: Some individuals may experience temporary redness or irritation post-treatment.

• Multiple sessions: One session will rarely achieve optimal results; multiple visits are necessary for most people.

• Cost implications: Although prices are falling, laser hair removal still represents a significant investment for some.

Understanding these aspects will help UK consumers decide whether laser hair removal aligns with their expectations, budget and comfort levels. In the following sections, we’ll delve deeper into how the technology works, explore different laser types, and offer guidance on selecting reputable clinics. By the end of this guide, you should have the confidence and knowledge to determine if laser hair removal is right for your specific needs.

How laser hair removal works

Laser hair removal utilises concentrated beams of light to target the melanin in hair follicles. Each pulse of laser energy is designed to be absorbed primarily by the hair’s pigment, generating heat that damages or destroys the follicle’s ability to produce new hair. This process, known as selective photothermolysis, allows the laser to isolate and affect only the hair while minimising damage to the surrounding tissue. Understanding this principle is fundamental for anyone considering laser treatments.

The procedure is straightforward in concept: a handheld device emits laser light at a specific wavelength. The melanin in the hair follicle absorbs this energy and converts it into heat. Over multiple treatments, these thermal effects weaken the follicle’s capacity to regenerate hair. Because follicles go through different growth phases—anagen (active growth), catagen (transitional) and telogen (resting)—multiple sessions are required to capture each follicle at its most vulnerable point: the anagen phase.

The role of melanin

• Eumelanin: Present in dark hair, absorbs laser energy efficiently, making laser hair removal most effective for individuals with darker hair.

• Pheomelanin: Found in lighter or red hair, may not absorb the laser energy as effectively, necessitating alternative wavelengths or multiple sessions.

Tip: Although darker hair is typically more responsive, advancements in technology have broadened the range of treatable hair colours and skin types.

Factors influencing treatment success

• Skin type: Fitzpatrick Scale classification (ranging from very fair to very dark) helps practitioners tailor the laser’s intensity and wavelength.

• Hair density and thickness: Thicker, coarser hair tends to respond well, but requires careful laser settings to avoid discomfort or irritation.

• Hormonal status: Conditions like polycystic ovary syndrome (PCOS) can stimulate excess hair growth, potentially affecting laser outcomes.

• Clinic equipment and technique: Skilled practitioners with modern machines can optimise results and reduce side effects.

Hair growth cycle overview

Addressing common misconceptions

• Instant result: Although each session damages many follicles, results become noticeable only after several treatments.

• Complete and permanent removal: The term “permanent hair reduction” is more accurate. Some follicles may regrow over time, though typically finer and lighter.

• One-size-fits-all solution: Laser settings must be adjusted according to individual factors—there is no universal laser hair removal approach.

An understanding of these underlying principles helps manage expectations and informs decision-making. As technology evolves, UK clinics can offer increasingly precise treatments, ensuring patients benefit from a comfortable experience and more definitive hair reduction over time. In the next section, we explore the various laser technologies used in clinics, highlighting why the right device matters greatly for safety and efficacy.

Types of laser technology

Laser hair removal systems differ primarily in their wavelength, pulse duration and overall design. Each technology suits particular skin tones, hair colours and body areas. In the UK, clinics typically offer one or more laser types to accommodate diverse needs. Understanding the equipment can help you make an informed choice, especially if you have a specific hair or skin type that might respond better to one system over another.

Common laser systems in UK clinics

1. Alexandrite (755 nm wavelength)

   • Often considered suitable for lighter skin tones (Fitzpatrick I-III).

   • Highly effective at targeting the melanin in darker hair.

   • Sessions can be relatively quick due to a faster pulse repetition rate.

2. Diode (800–810 nm wavelength)

   • A versatile option known for its penetration depth, making it suitable for a range of skin types.

   • Can treat coarser, thicker hair effectively.

   • Often features advanced cooling systems to reduce discomfort.

3. Nd:YAG (1064 nm wavelength)

   • Favoured for darker skin tones (Fitzpatrick IV-VI) due to reduced melanin absorption in the upper skin layer.

   • Lower absorption in melanin also means it may require more sessions to achieve desired results on lighter hair.

   • Some patients find treatments slightly more uncomfortable due to the laser’s penetration depth.

4. Ruby (694 nm wavelength)

   • One of the earliest laser technologies for hair removal, now less common.

   • Effective on fine, lighter hair but typically limited to lighter skin tones due to higher melanin absorption in the skin.

   • Slower repetition rates mean treatment sessions can be longer.

Key considerations when comparing lasers

• Wavelength: Determines how deeply the laser energy penetrates and which skin tones can be safely treated.

• Pulse duration: Short pulses can effectively target smaller follicles, whereas longer pulses may better suit larger follicles and darker skin.

• Spot size: A larger spot size speeds up treatment sessions on extensive body areas like the legs or back.

• Cooling systems: Help counteract the heat from the laser, reducing discomfort and the risk of burns.

Bullet points: factors influencing the choice of laser

• Skin and hair colour: The closer the match between hair melanin and the laser’s wavelength, the more effective the treatment.

• Treatment area: Smaller spot sizes suit delicate areas like the upper lip, while larger sizes expedite bigger regions such as the back or legs.

• Pain tolerance: Cooling features and advanced technology can lessen discomfort, but individual sensitivity varies.

• Budget and clinic availability: Some lasers are more advanced—and potentially more expensive—than others.

Typical uses for each laser type

¹ Subjective assessment, often mitigated by advanced cooling features.

As UK clinics continue to expand their laser offerings, the availability of these technologies makes it possible for most individuals to find a suitable match. It’s also not unusual for practitioners to recommend a combination of lasers if your skin or hair characteristics evolve—especially in cases where hormonal changes might alter hair growth patterns. Ultimately, a thorough consultation will determine which technology is the most effective and safest option for you.

Potential benefits and drawbacks

Laser hair removal promises a smoother, low-maintenance alternative to traditional hair removal methods. However, like any procedure, it comes with both advantages and disadvantages. Being fully aware of these can help UK consumers make an informed decision tailored to their skin type, budget and personal preferences.

Key benefits

1. Long-term hair reduction

   • Reduced regrowth means that after a recommended course of treatments, many individuals notice significantly less hair over time.

   • Convenience is a major benefit; reduced hair growth often translates to minimal upkeep, sparing both time and effort in the long term.

2. Precision targeting

   • Modern lasers allow practitioners to target specific hair follicles without severely affecting the surrounding skin.

   • Particularly useful for treating small or sensitive areas, such as the upper lip or bikini line.

3. Less irritation

   • Temporary redness can occur, but many find it less aggravating than the nicks, bumps and ingrown hairs frequently caused by shaving or waxing.

   • Over multiple sessions, the reduction in coarse hair often alleviates ongoing issues like razor burn.

4. Customisable treatment plans

   • Different laser wavelengths and cooling systems mean sessions can be tailored to accommodate varying skin tones and hair types.

   • Practitioners can adjust settings in real time if they observe potential complications or if the patient reports discomfort.

Common drawbacks

1. Multiple sessions required

   • Laser hair removal targets follicles in the active growth phase. Because not all hairs are in this phase at the same time, repeated sessions (typically 6–8) are necessary.

   • Maintenance sessions may be needed in the future to address any regrowth or dormant follicles that become active.

2. Cost considerations

   • Upfront costs can be high, particularly for large treatment areas like the back or legs. While the overall expense might be offset by long-term savings on waxing and shaving products, it remains a financial commitment.

   • Package deals often provide cost savings, but it’s important to verify the reputation of the clinic before making any commitments.

3. Possible side effects

   • Mild swelling or redness is common immediately after treatment.

   • There is a risk of burns, blistering or changes in skin pigmentation if the laser is used incorrectly. Choosing a qualified practitioner greatly reduces these risks.

Table: comparing laser hair removal to traditional methods

Managing expectations

• Complete removal: While some people experience near-total elimination of hair, “permanent hair reduction” is the more accurate term.

• Maintenance: Occasional top-up sessions might be required, especially if hormonal fluctuations affect hair growth.

• Instant results: Hair typically falls out 1–2 weeks post-treatment, and substantial results often appear only after a series of sessions.

For those deciding whether to opt for laser hair removal, weighing these pros and cons is essential. The promise of long-term hair reduction and convenience must be balanced against the financial investment and multiple appointments. Additionally, potential side effects—though minimal when administered by trained professionals—should be recognised and addressed openly during consultations. In the following sections, we will explore how best to prepare for your first appointment and what to anticipate during the treatment process.

Preparing for laser hair removal treatments

Laser hair removal is most successful when the right pre-treatment steps are followed. Adequate preparation not only ensures safer and more comfortable sessions but also contributes to optimal results. By taking the time to learn what’s expected before your appointment, you can arrive at the clinic with greater confidence and peace of mind.

Short introduction to the preparation process

From the moment you decide to pursue laser hair removal, there are several key guidelines to keep in mind. Generally, a reputable clinic or practitioner will provide specific instructions unique to your skin type, hair colour and medical history. Nonetheless, the best outcomes often hinge on universal best practices, such as avoiding sun exposure, refraining from waxing and disclosing any medications you’re taking.

Common preparatory steps

1. Consultation and patch test

   • Most clinics will insist on a face-to-face consultation to evaluate your skin and hair type.

   • A patch test, usually conducted on a discreet area of skin, checks for adverse reactions or excessive sensitivity.

2. Avoid tanning

   • Sun exposure, tanning beds and self-tanners can increase melanin in the skin, heightening the risk of burns and hyperpigmentation.

   • As a rule of thumb, avoid direct sunlight or tanning for at least two weeks before your session.

3. Refrain from waxing or plucking

   • Laser hair removal targets the root, so removing hair from the follicle (via waxing or plucking) can compromise effectiveness.

   • Shaving the treatment area is usually permitted and often required a day or two before your session.

4. Skincare adjustments

   • Discontinue any harsh skincare regimens, particularly those involving chemical peels or exfoliants, at least a week prior.

   • Hydrate skin and ensure any dryness or irritation is resolved before treatment.

Additional considerations

• Medications: Some antibiotics or photosensitising drugs can increase the skin’s sensitivity to laser light. Inform your practitioner about all current medications.

• Hormonal factors: Hormone fluctuations—due to contraceptives or other medical conditions—might impact hair growth patterns and necessitate tailored advice.

• Lifestyle habits: Smoking and poor diet can affect skin health, which may indirectly influence treatment outcomes and healing times.

Managing your expectations

• Realistic time frame: Laser hair removal isn’t immediate. It requires patience, as multiple sessions spaced weeks apart are generally needed.

• Open communication: Alert your practitioner to any recent changes in your health, such as new medications or sudden skin irritations.

• Calm and focused: Feeling nervous is normal. If you have questions, ask. A quality clinic will welcome your queries and aim to put you at ease.

Proper preparation is more than a formality—it’s a key determinant of how well the laser can target your hair follicles and how comfortable your sessions will be. By following these guidelines diligently, you’ll create the best conditions for a successful, satisfying experience. Next, we’ll walk through the typical treatment process, breaking down what happens from start to finish and how you can anticipate each step of the session.

The treatment process and what to expect

Stepping into a clinic for your first laser hair removal session can feel both exciting and a little daunting. Having a clear roadmap of what unfolds during treatment can help you prepare mentally and physically. While individual experiences may vary based on personal factors and the type of laser used, the overarching framework of a laser hair removal session remains fairly consistent across reputable UK clinics.

Overview of a typical session

1. Pre-treatment discussion

   • Your practitioner will review your medical history, current medications and any relevant updates since your initial consultation.

   • A brief skin check may be performed to ensure there are no signs of rash, irritation or breakouts.

2. Skin preparation

   • The target area might be cleansed to remove makeup, oils or lotions.

   • A topical anaesthetic gel or cooling agent may be applied to minimise discomfort, although many modern lasers have built-in cooling systems.

3. Laser application

   • You and your practitioner will wear protective eyewear to shield your eyes from the laser light.

   • The laser device is then passed over the treatment area in a systematic pattern, delivering controlled pulses of light energy into the hair follicles.

   • Some patients describe the sensation as a ‘rubber band snap’ with mild warmth or tingling.

4. Immediate post-laser care

   • A soothing lotion or gel is often applied to calm the skin.

   • Ice packs or cooling devices may be used if you experience significant redness or swelling.

Managing discomfort and sensations

• Cooling mechanisms: Advanced lasers feature cooling tips or pulsed cooling sprays that help regulate skin temperature.

• Topical numbing creams: Useful for areas with denser hair follicles, such as the underarms or bikini line, but must be applied judiciously to avoid excessive skin desensitisation.

• Breaks: Practitioners can pause treatment briefly if it becomes uncomfortable, allowing you to regroup.

After the session

• Redness and mild swelling: Common but usually short-lived, often subsiding within a few hours to a day.

• Shedding phase: Over the next 1–2 weeks, treated hairs may appear to ‘grow’, but this is typically the follicle pushing out the destroyed hair shaft.

• Follow-up scheduling: Your practitioner will advise on the interval until the next session, generally 4–6 weeks.

Tips for a smoother treatment experience

• Arrive on time: Late arrivals might rush pre-treatment care, reducing effectiveness.

• Avoid caffeine: Excessive caffeine intake can make some people more sensitive to pain.

• Dress comfortably: Wear loose-fitting clothing to reduce friction on the treated area post-session.

Each appointment builds on the previous one, gradually affecting more hair follicles that enter the active growth phase. As you progress through your course of treatments, you’ll likely notice increasingly thinner, lighter hair regrowth. The next section focuses on aftercare essentials and how to handle possible side effects—important information for maintaining healthy skin and optimising results after each session.

Aftercare and possible side effects

Once a laser hair removal session concludes, proper aftercare is crucial for supporting your skin’s recovery and maintaining the treatment’s effectiveness.

Frequently asked questions

Understanding the basics

What is laser hair removal?

Laser hair removal is a cosmetic procedure that uses concentrated light to target and damage hair follicles. Over multiple sessions, it reduces hair regrowth, often leading to smoother skin compared to traditional methods like shaving or waxing.

How does laser hair removal actually work?

Laser devices emit pulses of light that are absorbed by the melanin (pigment) in the hair. This energy converts to heat, disabling the follicle and reducing future growth. Different wavelengths can be used to suit various skin tones and hair types.

Is it the same as IPL?

No. Although Intense Pulsed Light (IPL) also uses light to target hair, it operates across a broader wavelength range. Lasers focus on a single wavelength, which often provides more precision and potentially faster, more consistent results.

Does laser hair removal offer permanent results?

The term “permanent reduction” is more accurate. Many people experience long-term reduction in hair growth, but occasional top-up sessions may be needed. The results vary based on individual factors like hormone levels and hair type.

Preparation and eligibility

Who is the ideal candidate for laser hair removal?

Anyone with unwanted hair is a potential candidate, but those with dark hair and lighter skin generally see the fastest results. Modern lasers can accommodate a range of skin tones and hair colours, although certain conditions and medications may require extra caution.

Why do I need a patch test?

A patch test helps assess how your skin reacts to the laser. It reduces the risk of side effects like burns or pigmentation issues by ensuring the laser settings are suitable for your skin type.

Can I wax or pluck before my session?

It’s best to avoid hair removal methods that pull the hair from the root. The laser targets hair follicles in the active growth phase, and waxing or plucking can disrupt this. Shaving the area is typically allowed and often recommended.

Should I stop using topical creams or lotions?

You may be asked to pause certain skincare products—particularly those containing strong acids or retinoids—a few days before your session. These products can irritate or sensitise the skin, increasing the risk of redness or discomfort.

During the procedure

What happens during a typical treatment session?

A laser technician or medical professional will cleanse the area, apply a cooling gel or use a built-in cooling mechanism, and deliver targeted pulses of light. You’ll wear protective eyewear, and most sessions last from a few minutes to an hour, depending on the treatment area.

Will it hurt?

Discomfort levels vary. Many describe it as a snapping sensation against the skin. Modern systems have improved cooling features to reduce pain. You can also discuss topical anaesthetic creams with your practitioner for sensitive areas.

Do I need protective eyewear?

Yes. Both you and the practitioner should wear protective eyewear to shield your eyes from the laser’s intense light, which could cause eye damage if viewed directly.

Can I treat multiple areas in one appointment?

Yes, multiple areas—such as the underarms, bikini line and legs—can be treated in a single session. The total time depends on how many areas you choose to include.

Aftercare and results

How long until I see results?

Some hair sheds within a week or two post-treatment. Noticeable reduction usually emerges after several sessions, as each appointment targets hair follicles in the active growth phase.

Can I sunbathe after laser hair removal?

It’s generally advisable to wait at least two weeks before prolonged sun exposure or using tanning beds. Sunburned or recently tanned skin has a higher risk of pigmentation changes and laser-related burns.

What if redness or swelling persists?

Mild redness and swelling around hair follicles are normal and usually subside within a day or two. Applying a cold compress or soothing lotion helps reduce inflammation. If you notice excessive redness, blistering or pain, contact your practitioner or GP.

Why is my hair “growing” after the session?

This is often the shedding phase. The damaged hair is being pushed out of the follicle, which can appear as growth. It typically sheds within a couple of weeks, revealing smoother skin.

Common concerns

Is laser hair removal safe for teenagers?

While there’s no universal rule against it, hormonal changes during adolescence can affect hair growth patterns. Many clinics recommend waiting until hormone levels stabilise to achieve more consistent, lasting results.

Can pregnant or breastfeeding women have laser hair removal?

There’s limited data on laser use during pregnancy or while breastfeeding, so many practitioners suggest postponing. Hormonal fluctuations can also make hair growth less predictable.

Will my skin tone affect the outcome?

Darker skin tones may require specific laser wavelengths (like Nd:YAG) to reduce the risk of pigmentation issues. Always ensure you choose a clinic experienced in treating a variety of skin types.

Can I have laser hair removal if I have tattoos in the area?

Laser hair removal can interact with tattoo pigments, potentially causing fading or discolouration. Practitioners typically work around tattoos or recommend alternative methods to avoid damaging the artwork or causing skin reactions.

Are there any risks of scarring or burns?

Laser hair removal is generally low risk if performed by a qualified professional. However, incorrect settings or poor aftercare can lead to burns, scarring or changes in pigmentation, so it’s vital to follow pre- and post-treatment guidelines.

Can hormonal conditions like PCOS affect treatment?

Yes. Conditions like polycystic ovary syndrome (PCOS) can stimulate excessive hair growth. Laser hair removal can still be effective, but more sessions or ongoing maintenance may be needed to manage hormonally driven regrowth.

How do I pick a reputable UK clinic?

Look for clinics registered with bodies like the Care Quality Commission (CQC) or those that hold accreditations from professional organisations. Check reviews, verify the practitioners’ qualifications, and insist on a consultation and patch test before committing.

Is laser hair removal worth the cost?

Many find the long-term convenience and reduction in daily hair-removal efforts justify the investment. Package deals often reduce the per-session cost, making it more affordable over time compared to the ongoing expense of razors or waxing.

Still have questions?

If you’ve read through this guide and find yourself with lingering doubts or specific questions about your personal circumstances, it may be time to seek expert advice. Speaking directly with a specialist can help clarify any unique considerations you might have—such as hormonal factors, a history of skin conditions or concerns about financing. An expert can provide you with personalised guidance, ensuring you feel fully confident in your decision-making process.

Glossary

Active growth phase (anagen)

This is the phase in the hair growth cycle when hair is actively growing and most susceptible to laser hair removal. The follicle is fully attached to its blood supply, allowing the laser to deliver energy directly to the root.

Alexandrite laser

A type of laser operating at a 755 nm wavelength. It’s often favoured for lighter skin tones, as it effectively absorbs melanin in the hair shaft. Alexandrite lasers can treat large areas quickly due to their rapid repetition rate.

Anaesthetic cream

A topical numbing agent applied to the skin before laser hair removal. It helps minimise discomfort by temporarily desensitising nerve endings, although it should be used judiciously to avoid over-application or skin irritation.

Beam size

The diameter of the laser beam that hits the skin. A larger beam size can cover more area in a shorter time, making treatments faster, especially when treating large zones like the legs or back.

Bikini area

A commonly treated region for laser hair removal, encompassing the sides of the pubic region and sometimes extending to a fuller bikini line. Sessions may be customised according to personal preference and comfort.

British Medical Laser Association (BMLA)

A UK-based organisation dedicated to promoting safe and effective medical and aesthetic laser practices. Membership indicates adherence to industry standards and ongoing professional development.

Care Quality Commission (CQC)

The independent regulator for health and social care services in England. Clinics offering certain laser treatments may require CQC registration, assuring compliance with safety and quality standards.

Catagen phase

A brief transitional period in the hair growth cycle during which the follicle detaches from its blood supply. Laser hair removal is less effective in this phase, as the follicle is no longer actively growing.

Chromophore

A target molecule in the skin or hair that absorbs specific wavelengths of light. In laser hair removal, melanin acts as the chromophore, converting light energy into heat to damage the hair follicle.

Consultation

An in-person or virtual meeting where a practitioner assesses suitability for laser hair removal, discusses medical history and expectations, and performs a patch test to gauge skin reaction.

Cooling gel

A product applied to the skin before or during laser treatment to reduce the sensation of heat and protect the epidermis. It also enhances light transmission by creating better contact between the skin and the laser device.

Cryogen spray

A specialised cooling spray emitted by some laser systems to minimise discomfort and protect the top layer of skin from excessive heat during each laser pulse.

Diode laser

A laser that typically operates around an 800–810 nm wavelength. It is versatile across multiple skin types, penetrates deeper into the hair follicle and is often paired with cooling technology for comfort.

Downtime

The recovery period after a laser hair removal session. While most individuals can resume normal activities immediately, some experience mild redness or irritation for a few hours to a day.

Electrolysis

A hair removal method predating laser technology that involves inserting a tiny needle into each hair follicle and delivering an electric current. It can be effective for lighter hair colours less responsive to laser light.

Fitzpatrick scale

A classification system that categorises human skin based on its response to UV light. Ranging from Type I (very fair) to Type VI (deeply pigmented), it helps practitioners tailor laser settings for optimal safety and efficacy.

Follicle

A small organ in the skin that produces hair. Laser hair removal targets the follicle’s root when it is in anagen (active growth), ultimately reducing its capacity to regrow hair.

Hair density

The amount of hair within a specific area of skin. Higher density areas may require more laser pulses or slightly longer sessions. Density can also affect how quickly results become noticeable.

Hair growth cycle

A sequence of phases—anagen, catagen and telogen—through which each hair passes. Laser treatments are most effective when the hair is in the anagen phase because the follicle is fully active.

Hyperpigmentation

A side effect characterised by patches of skin becoming darker than the surrounding area. This can occur if excessive laser energy is absorbed by the skin, leading to increased melanin production.

Hypopigmentation

The opposite of hyperpigmentation, where treated skin appears lighter due to the reduction or loss of melanin in the area. Though less common, it may arise if the laser’s settings were too intense or if the skin was highly sensitive.

Informed consent

The process where patients receive clear information about a medical or cosmetic procedure, including its risks, benefits and alternatives, allowing them to agree to treatment with full understanding.

Intense pulsed light (IPL)

A light-based technology sometimes used for hair removal. Unlike laser devices, IPL machines emit a broad spectrum of wavelengths, making it less specific but still effective for some individuals.

Joint Council for Cosmetic Practitioners (JCCP)

A UK regulatory body that maintains a register of approved cosmetic practitioners. Membership reassures patients that safety, training and ethical standards are met for procedures like laser hair removal.

Laser

A device that emits focused light at a specific wavelength to target and damage hair follicles selectively. Different lasers—such as Alexandrite, Diode and Nd:YAG—suit various skin and hair types.

Laser safety glasses

Protective eyewear worn by both the patient and practitioner during treatment. They block or reduce specific wavelengths to prevent eye damage from the laser beam.

Laser wavelength

The specific measurement (in nanometres) at which the laser operates. This determines how deeply the laser energy penetrates the skin and how effectively it targets melanin in the hair shaft.

Maintenance session

A follow-up laser hair removal treatment performed after the initial series of sessions. It helps manage any slight regrowth and maintain smoothness over time.

Melanin

A natural pigment found in skin and hair. Melanin concentration in the hair shaft is crucial to laser hair removal; more melanin typically means better absorption of laser energy.

Nd:YAG laser

A long-wavelength laser (1064 nm) often used for darker skin tones, as it penetrates deeper and has less interaction with melanin in the upper layers of skin. This lowers the risk of burning or discolouration.

Patch test

A small trial of the laser on a discreet section of skin to assess reaction and determine the appropriate settings. This step helps minimise side effects and ensures safety for the full treatment area.

Photosensitivity

A heightened sensitivity to light. Certain medications or medical conditions can increase photosensitivity, making the skin more prone to burns or pigmentation changes during laser treatment.

Post-inflammatory hyperpigmentation (PIH)

A temporary condition where darker patches of skin appear after an inflammatory reaction, such as laser treatment. Most cases fade over time, but prevention through correct laser settings is key.

Protective eyewear

Specialised goggles or shields to safeguard both the patient’s and practitioner’s eyes from direct and scattered laser light, essential for preventing retinal damage.

Redness

A common, short-lived side effect following laser sessions. Mild redness may resemble a sunburn and typically subsides within a day or two, especially with proper aftercare.

Resting phase (telogen)

The final part of the hair cycle before shedding. Hair in the telogen phase is less responsive to laser treatment, as it’s disconnected from the follicle’s blood supply.

Selective photothermolysis

The principle behind laser hair removal. It refers to the laser’s ability to selectively target hair follicles based on their melanin content while sparing surrounding tissues.

Side effects

Unintended reactions that can follow laser hair removal, including redness, swelling, mild discomfort, and in rare cases, burns or changes in pigmentation. Proper technique and aftercare mitigate these risks.

Skin cooling

Methods or devices—like chilled tips, cryogen spray, or cooling gels—used during laser sessions to protect the epidermis and improve patient comfort.

Tanning

Natural or artificial darkening of the skin, often caused by UV exposure. Tanned skin can increase laser hair removal risks, such as burns or uneven pigmentation, due to elevated melanin levels.

Thermal relaxation time

The time it takes for heated tissue to disperse at least 50% of the heat gained during laser exposure. Understanding thermal relaxation time helps practitioners minimise damage to surrounding skin.

Treatment interval

The recommended span between laser hair removal sessions, often 4–6 weeks, allowing the skin to recover and additional hair follicles to enter the active growth phase for effective targeting.
