Let’s Talk Laser Hair Removal

Updated: Nov 1, 2019

The aesthetic and cosmetic industry is comprised of various procedures that help individuals improve different aspects of an individual’s appearance. Due to the introduction and development of new procedures and technologies, the aesthetic industry is continuously changing. However, one constant that has remained over the years is the growing popularity of laser hair removal.

How Hair Removal Works

Thanks to advanced light-based technologies, shaving, waxing, plucking, and other bothersome hair removal methods are becoming a thing of the past. Unlike these traditional methods that require constant upkeep and maintenance, laser hair removal attacks the root of the problem (literally) and delivers long-lasting and sometimes permanent hair reduction with just a few treatments. Laser hair removal works by destroying the root of the hair follicle. During treatment, flashes of light are distributed over the skin and absorbed by the melanin in the hair follicle. The energy from the laser heats up and damages the hair follicle, successfully stunting the cells that stimulate regrowth. It is important to note that hair grows in a cycle, and that hair removal is only effective during the active growth stage. There are three stages of growth that every hair goes through the anagen phase, catagen phase, and telogen phase. Each hair in your body can be at a different stage in the growth cycle at any given time. For example, one strand may be in the anagen phase, while another may be in the catagen phase.

The Anagen Phase The anagen phase, also known as the growth stage, is the duration in which your hair actively continues to grow. During this stage, the papilla, a structure at the base of the hair follicle, supplies nutrients to nourish hair growth. This stage can last anywhere from two to seven years. The Catagen Phase The catagen phase, also known as the transitional phase, is when the hair follicle shrinks and detaches from the papilla, cutting off its main supply of nourishment.This phase lasts about 10 days to two weeks. The Telogen Phase The telogen phase, also known as the resting phase, is when the old hair is released and falls out. When the old hair sheds, the hair follicle re-attaches to the papilla and re-enters the anagen phase, repeating the cycle. To target the hair during the anagen phase, multiple laser treatments are necessary to target the numerous hair follicles during their growth stage. Most patients need 4 to 6 treatments to remove all hair and achieve long-lasting removal results. Depending on the technology being used, light-based hair removal is safe to use on all parts of the body. However, not all laser or light-based systems can deliver permanent hair reduction on all skin types and hair colors as effectively as others. Because laser hair removal targets the pigmentation in the hair follicle, patients with dark hair and light skin respond best to treatment. That being said, some laser clinics are unable to treat light blonde or grey hairs on light-skinned patients. Astanza Laser hair removal systems can safely and effectively treat all hair colors from all skin types and generate smooth, long-lasting skin results.
