If you are tired of shaving, waxing, or constantly dealing with ingrown hairs, laser hair removal can make everyday life much easier. For many people, it reduces the time, irritation and frustration associated with traditional hair removal.
If you are tired of shaving, waxing, or constantly dealing with ingrown hairs, laser hair removal can make everyday life much easier. For many people, it reduces the time, irritation and frustration associated with traditional hair removal.
But it is important to start with realistic expectations. Laser hair removal can provide significant long‑term hair reduction, yet it does not guarantee that every hair will disappear permanently for everyone.
Many marketing pages simplify this point. In reality, results depend on several factors: the colour and thickness of the hair, skin tone, the area being treated, the device used and — most importantly — how well the treatment settings are adapted to your skin and hair.
The most accurate way to describe laser hair removal is therefore simple: it is an effective treatment for long‑term hair reduction when the protocol is carefully tailored to the patient and expectations remain realistic.

What is laser hair removal?
Laser hair removal is a procedure that uses concentrated light to target the pigment (melanin) inside the hair. The energy from the laser converts into heat, which damages the hair follicle and slows future growth.
The goal is not simply to remove the visible hair above the skin. The treatment targets the follicle structures responsible for hair regrowth, which is why the effect builds gradually over time.
Because hairs grow in different phases, several sessions are necessary. Only hairs in the active growth phase respond effectively to the laser during each session.
In general, the best results are seen in dark, relatively coarse hair. Very light blonde, white, grey or red hair often responds poorly — or sometimes not at all — because there is too little pigment for the laser to target.
How does laser hair removal work?
Laser hair removal works through a principle called selective photothermolysis. In simple terms, the laser energy is designed to target pigment in the hair more strongly than the surrounding skin.
For the treatment to be both effective and safe, several parameters must be adjusted carefully:
- wavelength
- energy level (fluence)
- pulse duration
- cooling system
- skin phototype
- hair colour and thickness
These variables explain why two people receiving treatment on the same body area may still experience very different outcomes.
Does laser hair removal really work?
Dermatology reviews and systematic analyses consistently show that laser and light‑based devices can produce significant long‑term hair reduction after multiple sessions.
Yes. Scientific research consistently supports laser hair removal as an effective way to reduce unwanted hair over the long term.
However, it is important to understand what “effective” means. The goal is usually long‑term hair reduction, not necessarily complete and permanent removal of every hair.
Most patients notice:
- fewer hairs
- finer regrowing hairs
- slower regrowth
- occasional need for maintenance sessions
Clinical studies show meaningful reduction after multiple sessions, although results vary depending on the device used, the treatment area, skin type and hormonal background.
In practice, good improvement is common. What responsible providers avoid promising is “100% permanent results”, “one session only” or “hair removal for life”.
What results can you realistically expect?
Most people see a gradual reduction in hair density over the course of treatment. When hair does regrow, it is often finer, lighter and slower to return.
Some areas of the body typically respond better than others. Underarms, bikini line and legs often show strong results. Facial areas can be more unpredictable, especially when hormonal factors influence hair growth.
A good outcome does not always mean completely hair‑free skin. For many patients, the real benefit is already significant: less regrowth, fewer ingrown hairs and much less maintenance in everyday life.

How many laser hair removal sessions are needed?
There is no universal number of sessions. The ideal treatment plan depends on the body area, the hair growth cycle, hair thickness, skin phototype and the device used.
Most people require multiple sessions spaced over several months. Some achieve strong reduction after a standard initial series, while others may need a longer course or periodic maintenance sessions — particularly on the face or when hormonal factors are involved.
In simple terms: laser hair removal is a progressive treatment, not an instant result.
Who is a good candidate?
Historically, the best candidates have lighter skin combined with dark, coarse hair. The strong contrast helps the laser target the hair pigment more selectively.
However, darker skin tones can also be treated safely today when the correct device and settings are used by experienced practitioners.
When hair is very light blonde, white, grey or red, laser treatment becomes much less effective. In those situations, electrolysis is often the better option.
What types of devices are used?
Different laser systems exist, and not every device is suitable for every patient.
Alexandrite 755 nm
Often used for lighter to intermediate skin tones with dark hair. It can produce excellent results but requires careful patient selection and appropriate settings.
Diode 800–810 nm
One of the most widely used laser systems in clinical practice. It offers a good balance between effectiveness and safety and can treat several skin phototypes depending on the device and operator experience.
Nd:YAG 1064 nm
Frequently preferred for darker or more pigmented skin types because it reduces the risk of epidermal injury when used correctly.
IPL
IPL (intense pulsed light) is not technically a laser. It emits broad‑spectrum light and can reduce hair growth, but results are often less precise and less consistent than those achieved with a medical laser.
Darker skin: correct technique matters
The idea that laser hair removal “does not work on darker skin” is incorrect. The reality is that treatment simply requires greater precision and appropriate technology.
Darker skin types should be treated using suitable devices, carefully chosen parameters and practitioners experienced with these phototypes.
The real risk is not skin colour itself but using the wrong device or settings, which can increase the likelihood of burns or pigment changes.
Belgium and Europe: what patients should know
In Europe, high‑energy hair removal devices are regulated more strictly than typical cosmetic tools. They fall within the framework of the European Medical Device Regulation (MDR) and related rules covering certain aesthetic devices.
For patients in Belgium, one point is often misunderstood: laser hair removal does not always need to be performed personally by a physician. Depending on the setting, trained non‑physicians may perform the treatment.
What matters most is the quality of training, proper patient evaluation, safe equipment and the ability to recognise and manage potential complications.
In other words, the key factors are training, experience, patient selection and treatment safety.
What happens during a session?
Before treatment, the area is usually shaved if necessary and cleaned. Both the patient and practitioner wear protective eyewear. Some systems also use cooling technology, gel or cold air to protect the skin and improve comfort.
The practitioner adjusts the settings according to the treatment area, skin type and hair characteristics. The laser is then applied in a series of pulses across the area.
Most people describe the sensation as a quick elastic‑band snap or a brief burst of heat. It may not be pleasant, but most patients tolerate it well.
After treatment, mild redness and slight swelling around the follicles are common. These reactions are expected and usually temporary.
How should you prepare for laser hair removal?
A proper consultation should include an assessment of your skin type, hair characteristics, medications, medical history and previous reactions to cosmetic procedures before treatment begins.
Proper preparation improves treatment safety and results.
Proper preparation improves treatment safety and results.
Before a session, patients are usually advised to:
- avoid tanning or intense sun exposure
- avoid waxing, tweezing or epilating for several weeks
- shave the area according to clinic instructions
- inform the practitioner about photosensitising medications
- mention any history of herpes, pigmentation disorders or skin reactions
An important point often overlooked: when facial hair in women appears suddenly, worsens quickly or seems hormonally driven, a medical evaluation may be useful. Laser can reduce visible hair but does not treat underlying hormonal causes.
Recovery and aftercare
Recovery is generally quick and uncomplicated. Mild redness, warmth or sensitivity may last from a few hours to a few days.
After treatment, patients are usually advised to:
- protect the treated area from sun exposure
- apply appropriate sunscreen when necessary
- avoid excessive heat or irritation for a few days
- shave between sessions if needed, but avoid removing hairs from the root
Most people return to normal activities immediately.
Side effects and risks
Laser hair removal is considered safe when performed correctly. Dermatology societies consistently emphasize that proper patient assessment, appropriate device selection and trained operators are key factors for safe treatment.
Serious complications are uncommon when treatment is carried out by experienced professionals using appropriate technology.
Laser hair removal is considered safe when performed correctly. Serious complications are uncommon when treatment is carried out by trained professionals using appropriate devices.
Common temporary effects include:
- redness
- warmth
- slight follicular swelling
- temporary discomfort
More significant complications can occur if the device or settings are inappropriate:
- burns
- blisters
- crusting
- hyperpigmentation or hypopigmentation
- scarring (rare)
- eye injury without proper protection
Another less widely known effect is paradoxical hypertrichosis, where hair growth is stimulated rather than reduced. This phenomenon is uncommon but documented, particularly in facial areas and certain hormonal profiles.
Special situations: rosacea, eczema, hyperpigmentation, tattoos and pregnancy
Many patients wonder not only whether laser hair removal works, but whether it is suitable for their specific situation.
Laser hair removal and rosacea
Treatment may sometimes be possible, but active rosacea flare‑ups or very reactive skin require caution. Facial treatment should ideally be performed by practitioners experienced with sensitive skin.
Laser hair removal and eczema
Treatment is usually avoided on areas with active eczema. Inflamed or irritated skin tolerates heat and friction poorly. When eczema is controlled, treatment may sometimes be possible.
Laser hair removal and hyperpigmentation
Skin prone to pigmentation requires careful device selection, conservative settings and strict sun protection before and after treatment.
Laser hair removal and tattoos
Laser hair removal should not be performed directly over tattooed skin because tattoo pigment can absorb the laser energy and cause burns or damage the tattoo.
Laser hair removal during pregnancy
Most clinics recommend postponing treatment during pregnancy as a precaution. This is mainly due to limited safety data rather than proven harm.
Laser hair removal during breastfeeding
Policies vary between clinics. If treatment is not urgent, many providers prefer to wait until after breastfeeding.
PCOS, hirsutism and hormonal conditions
Laser hair removal can significantly improve visible hair growth but does not treat the hormonal cause. If hair growth appears suddenly or worsens rapidly, medical evaluation may be helpful.

Can laser hair removal have medical benefits?
Yes. Beyond cosmetic improvement, laser hair removal can help conditions such as recurrent ingrown hairs or pseudofolliculitis — especially in individuals prone to irritation from shaving.
For some patients, this improvement can meaningfully enhance comfort and quality of life.
What are the alternatives?
Electrolysis
Often the best option for light, grey, white or red hairs or when treating a small number of individual hairs. It is slower but can be more suitable in these cases.
IPL
Can provide hair reduction in some situations but is generally less precise and less consistent than medical laser treatment.
Traditional hair removal
Shaving, waxing and mechanical epilation remain useful for maintenance but do not provide long‑term reduction.
At‑home devices
Home devices can offer modest reduction but their power and clinical evidence differ significantly from professional treatments.
How to choose a good laser hair removal clinic
Choosing a clinic should not rely solely on the brand of machine advertised online.
More meaningful indicators include:
A thorough consultation
Your skin, hair characteristics, medical history and expectations should be evaluated.
Appropriate technology
The clinic should explain why a particular device suits your skin and hair.
Personalised settings
Even the best laser device is ineffective with poor settings.
Experience with your skin type
This is particularly important for medium, olive or darker skin tones.
Honest communication
Be cautious of clinics promising instant or guaranteed permanent results.
At iGlowly, our treatment guides aim to explain aesthetic procedures using current medical literature and real clinical practice rather than marketing promises.
Laser hair removal is a well-established and effective option for long-term hair reduction.
Laser hair removal is a well‑established and effective option for long‑term hair reduction. When performed correctly, it can significantly reduce unwanted hair, minimise ingrown hairs and simplify daily grooming.
However, the treatment is not simply “a laser session”. It is a carefully selected, properly adjusted and professionally supervised procedure tailored to your skin and hair characteristics.
In Belgium and across Europe, the key question is therefore not only which device is used, but also who performs the treatment, how the settings are determined and how safety is ensured.
