Laser hair removal uses concentrated light energy to target and destroy hair follicles, preventing future hair growth. The laser emits a specific wavelength of light that is absorbed by the melanin (pigment) in the hair shaft and follicle. The heat generated destroys the follicle's ability to produce new hair, resulting in permanent hair reduction over a course of treatments.
Multiple sessions are required because hair grows in cycles — the laser is only effective on hairs in the active growth phase (anagen). A course of 6–8 sessions typically achieves 80–90% permanent reduction, with annual top-up sessions recommended to treat any regrowth.
Laser hair removal works best on dark hair against light skin, as the contrast allows the laser to target melanin in the hair without damaging the surrounding skin. Modern diode lasers and Nd:YAG lasers have made the treatment safer and more effective for darker skin tones (Fitzpatrick types IV–VI), but require specific wavelength settings and an experienced practitioner.
Laser hair removal on tanned or darker skin tones carries a higher risk of burns, blistering, and hyperpigmentation if the wrong laser or settings are used. Always ensure your practitioner uses a laser appropriate for your skin type and has specific training in treating your Fitzpatrick skin type. Avoid treatment if you are pregnant, have a photosensitive skin condition, or are taking photosensitising medications.

Ensure the clinic uses a medical-grade laser (not an IPL device, which is less effective and less safe). Ask about the specific laser technology used, the practitioner's training, and their experience treating your skin type. A patch test should always be performed before a full course of treatment.
