Laser hair removal is a medical procedure that uses a concentrated beam of light i.e. laser to remove unwanted hair. During laser hair removal, a laser emits a light that is absorbed by the pigment melanin which is present in the hair. The light energy is then converted into heat, which damages the hair follicles that produce hairs. This damage inhibits or delays future hair growth. Laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment.
Laser hair removal has become popular because of its speed and efficacy, although some of the efficacy is dependent upon the skill and experience of the laser operator, and the choice and availability of different laser technologies used for the procedure. Some will need touch-up treatments, especially on large areas, after the initial set of 3-8 treatments.
Laser Hair Removal Procedure
Laser hair removal usually requires a series of two to six treatments. The interval between treatments will vary depending on the location. On areas where hair grows quickly, such as the upper lip, the treatment might be repeated in four to eight weeks. On areas of slow hair growth, such as the back, the treatment might be every 12 to 16 weeks. After the hair removal procedure, you might notice redness and swelling for the first few hours. To reduce any discomfort, apply ice to the treated area. If you have a skin reaction immediately after laser hair removal, the doctor might apply a steroid cream to the affected area. After laser hair removal and between scheduled treatments, avoid sun exposure: both natural sunlight and tanning beds for six weeks or as directed by your doctor. When hair re-grows, it’s usually finer and lighter in color. You might need maintenance laser treatments for long-term hair reduction.
