Τraditional hair removal techniques like shaving, plucking and waxing don't provide adequate results. Electrolysis often requires years of ongoing treatments. Laser hair removal (Alexandrite, ND-YAG or diode) works by targeting the pigment inside the hair follicle with very little damage to the delicate pores and structures of the skin. Because hair cycles through "growth" and "dormant" phases, and because during the "dormant" phase the follicle has no pigment, at least 6-8 treatments will be needed. The number of sessions will vary for each individual.
The area to be treated has to be trimmed before. A small handpiece is placed against the skin as the laser is activated. The probe is repositioned and the laser is activated again. The size or the area treated will determine the number of laser "pulses" required. Τhe last years the use of topical Eflornithine cream combined with the laser hair removal promises complete results (Xia Y, Cho S, Howard RS, Maggio KL. Topical eflornithine hydrocloride improves the effectiveness of standard laser hair removal for teating pseudofolliculitis barbae: a randomized, double-blinded, placebo-controlled trial. J Am Acad Dermatol. 2012 Oct;67(4):694-9).
Each "pulse" of laser light disables a large number of hair follicles. It treats the "active" follicles, even if the hair has not yet reached the surface of the skin, or if the hair shaft is not straight. While some areas of the body are more sensitive than others, most patients report little or no discomfort. For more sensitive patients, anesthetic creams or ice can be applied prior or after the treatment.
