Most lasers work by targeting the melanin in the hair follicle so the hairs must be present in the skin for the treatment to work. I usually instruct patients not to wax for at least 2-3 weeks prior to laser hair removal. The hairs do not have to be long (in fact it is better if they are short or freshly shaved) but nothing that removes the hair from the root (i.e. waxing, plucking, tweezing) should be done for at least a few weeks prior to treatment.
