Input: We included eleven randomised controlled trials involving 444 people, none of which were of high methodological quality. A large number of trials were excluded, mainly because of their non-randomised design. The randomisation procedures were either unclear or inadequate, using coin tossing, alternation, drawing lots or cards, or open tables of random numbers. The interventions and outcomes were too heterogeneous to be entered in a meta-analysis. Most trials examined a short-term effect up to six months after final treatment. There appeared to be a short-term effect of approximately 50% hair reduction with alexandrite and diode lasers up to six months after treatment, whereas little evidence was obtained for an effect of intense pulsed light, neodymium:YAG or ruby lasers. Long-term hair removal was not documented with any treatment. Pain, skin redness, swelling, burned hairs and pigmentary changes were infrequently reported adverse effects. Some treatments lead to temporary short-term hair removal. High quality research is needed on the effect of laser and photoepilation.
Output:

Eleven randomised controlled trials were included in the review, none of which were of high quality. A large number of trials were excluded, mainly because of their non-randomised designs. There appeared to be a short-term effect of approximately 50% hair reduction with alexandrite and diode lasers up to six months after treatment, whereas there was little evidence for an effect with intense pulsed light, neodymium:YAG or ruby lasers. Long-term hair removal was not recorded for any treatment. Infrequently reported adverse effects were pain, skin redness, swelling, burned hairs and pigmentary changes.
