Laser Hair Removal

Laser hair removal uses a beam of light absorbed by the pigment in the hair to disable the follicle, reducing regrowth over a course of sessions. Most clinics in the UK use diode, alexandrite or Nd:YAG lasers, and the right one depends on your skin tone and hair colour — which is why every course starts with a consultation and a patch test. IPL, an intense pulsed light rather than a true laser, works on the same principle and is often cheaper.

It works best on dark hair and is less effective on blonde, red, grey or white hair. Results build over six to eight sessions spaced four to eight weeks apart, as only hair in its active growth phase responds at each visit. Most people see a long-lasting reduction rather than total removal, with an occasional top-up session.

Small areas such as the upper lip or underarms take ten to fifteen minutes; full legs take closer to an hour. Shave the area the day before, and avoid tanning and sun exposure for several weeks either side of treatment. In London and in some other areas, laser and IPL premises need a local authority licence.
