During the last 10-15 years lasers have been used successfully for selectively destroying colored cells and blood vessels, and were therefore a logical choice for removing unwanted hair. Significant progress has been made in the last 2-3 years in refining the laser hair removal technique. Also, new topical medications and light-plus medication techniques are available today, or are currently under development for use in the near future.
Laser hair removal depends on the laser's ability to produce a brief, but intense temperature change confined primarily to the darkened root of the hair follicle, without causing any significant heating of the nearby surrounding tissues and skin.
Both long-term, lasting from 3-12 months, and permanent hair removal have been reported following a series of treatments over about a year. Results have been judged as "very satisfied" by more than 80-85% of treated patients. Most describe the benefits of less reliance on waxing, depilatories, shaving and other tedious and inconvenient older methods.
