What is Laser Hair Removal?
Laser hair removal has become one of the most popular cosmetic procedures in the United States. Each year over $650 million is spent on the procedure. Originally thought to totally remove hair, laser hair removal actually causes hair to lay dormant, where it cannot be seen. The process of laser hair removal has continued to improve as the laser technology has improved. It is today by far the most widely used high-tech method for hair removal. Laser hair removal techniques provide an extremely fast treatment time with little discomfort and less pain as compared to other hair removal methods like waxing. It provides long-lasting effects and since lasers work on removing multiple follicles at a single time, the process is much faster than other similar techniques.

Laser hair removal procedure is completed by bringing laser energy into the skin where hair follicles grow. The laser energy is attracted to hemoglobin that feeds the hair follicle and the pigment (melanin) in hair within the follicle. White or gray hair does not pull in the laser energy and generally will not be affected by the treatment. The hair follicles that are in the growing phase (anagen) will absorb the laser energy, heat will be produced and the follicle will die. A follicle in a resting phase (telogen) will not be attracted by the energy and thus will not be affected by the laser treatment. It is recommended that treatments be performed during these hair growth cycles. The number of treatments required usually depends on each patient’s expectations. An average person has approximately six growth cycles per year, therefore, you should expect treatments to last at least that period of time!
The laser hair removal on different parts of the body has established outstanding results in 60-80% of the cases in just two or three sessions. After the procedure, when the hair starts to grow back, it tends to be weaker and scattered. Results become more visible after more than one treatment, because only 20-30% of hair follicles are affected by one laser application. The procedure is used in the particular area that causes the hair growth, but it does not heat the skin around it. The laser procedure is based on directing the laser on the skin, where the laser light is absorbed by melanin found in the hair follicles. Once absorbed, the laser light is transformed into heat, destroying the part of the follicle that makes the hair grow.
