What is diode laser hair removal?
Diode laser hair removal is a medical-grade, non-invasive treatment that reduces unwanted hair by using targeted laser energy. The laser targets melanin (pigment) in the hair follicle, heating and damaging it to slow and reduce future hair growth.
This treatment provides long-term hair reduction, not permanent hair removal.
How does it work?
- The diode laser emits a concentrated beam of light
- The pigment in the hair absorbs the energy
- Heat damages the hair follicle while protecting surrounding skin
- Over time, treated follicles produce finer, slower-growing hair
Hair must be in the active growth phase (anagen) for treatment to be effective, which is why multiple sessions are required.
What areas can be treated?
Diode laser hair removal can be used on most areas of the face and body, including:
- Face (excluding eye area)
- Underarms
- Arms
- Legs
- Bikini and intimate areas
- Back
- Chest
- Abdomen
Our Specialist Nurse Prescriber will assess suitability based on skin type, hair colour, and the treatment area.
What will it feel like?
Most people describe the sensation as:
- A warm snapping or tingling feeling
- Mild to moderate discomfort
Modern diode lasers often include cooling systems to improve comfort.
How many treatments will I need?
- A course of 6–10 sessions is typically recommended
- Treatments are spaced 4–8 weeks apart, depending on the area
- Maintenance sessions may be required
Results vary between individuals.
What results can I expect?
- Gradual reduction in hair growth
- Hair grows back finer, lighter, and slower
- Some hairs may not respond to treatment
Laser hair removal works best on dark hair and is less effective on blonde, red, grey, or white hair.
Downtime and recovery
- Mild redness or swelling around follicles is common
- Skin usually settles within a few hours to 48 hours
- Most people can return to normal activities immediately
Possible side effects & risks
Common temporary effects include:
- Redness
- Swelling
- Warmth or sensitivity
Less common risks include:
- Blistering or burns
- Pigmentation changes (hyperpigmentation or hypopigmentation)
- Crusting or scabbing
- Rare scarring
These risks are reduced when treatment is performed by trained professionals and aftercare instructions are followed.
