Selective Photothermolysis (SPT) is the primary method of laser hair removal. As the laser passes over the skin, a specific wavelength of light is absorbed by the hair root and transformed into heat. The heat causes thermal destruction of the hair follicle, which ultimately destroys the hair root. Through SPT, patients of all skin colors experience safe and long-term hair reduction.
Any skin color can be treated, although different skin types are best treated with different lasers. Lighter skin is best treated with the Alexandrite laser. Darker skin types can only be safely treated with an Nd:YAG laser and should only be treated under the supervision of a dermatologist who specializes in laser surgery. Fortunately, all necessary state-of-the-art laser technology for achieving the best, safest results is available at DermSpecialists.
Successful laser hair removal requires pigmented hair. Unfortunately, blonde and gray hair cannot be successfully treated with laser technology.
Most patients see 80 to 90% permanent hair reduction in four to six treatments. Because hair grows in cycles, there may be some regrowth. If this occurs, a follow-up treatment should be scheduled. Laser hair removal patients generally experience no complications when correct pre-treatment preparation is followed.
