Laser hair reduction is achieved by using heat to disable the hair follicle and prevent re-growth. The bulb and bulge of the follicle are the areas believed to be responsible for re-growth; these areas are targeted by the laser. Hair reduction works when there is color, or pigment in the hair. The laser is attracted to the melanin (dark pigment) in the hair follicle. White or blonde hair does not respond to the laser. Hormones, diseases, medication, or other factors have an impact on the treatment outcome.
Multiple treatments (6-9 treatments) are required to achieve sufficient reduction in hair growth because each hair goes through 3 growth phases (anagen, catagen, and telogen) and only the hair follicle in the anagen growth phase can be disabled. Each hair passes through the growth phases independent of the neighboring hairs, so not all hairs will be in the same phase at the same time; thus, multiple treatments are required. Treatment interval recommendations are a general guideline. Your provider will customize your treatment intervals.
Facial hair: 6-8 week intervals between treatments. (Facial skin has significantly more hair follicles than the body. This is why you can see results within the first three to four treatments with shorter interval times.)
Body hair: 8-10 week intervals between treatments.
Back or Leg hair: 10-12 week intervals between treatments.
Anagen - Active Phase
The laser light is absorbed by the melanin in the hair shaft, reaching the bulb and disabling the hair follicle.
Catagen - Transitional Phase
Hair bulge & bulb are beginning to disengage from the hair shaft and treatment is not effective.
Telogen - Resting Phase
Hair bulge and bulb are disengaged from the hair shaft and treatment is not effective.
