How It Works:
Lasers produce beams of highly concentrated light. The light emitted by the LightSheer Diode laser is well absorbed by the pigment located in hair follicles. During treatment the laser light is pulsed for a fraction of a second and is absorbed into the targeted pigment in the hair shaft. Intense heat is created within the follicle and ultimately alters the surface of it permanently, which prevents new blood supply to nourish new growth.
A very important part of the procedure is the cooling of the skin. The LightSheer Diode laser has a special contact-cooling hand piece, which is patented, called the ChillTipTM. This hand piece has a 9mm square sapphire lens which actively cools and protects the upper layers of skin before, during and after each pulse, greatly increasing client comfort during treatment while the laser energy is directed at the hair root. This allows for safe and effective treatment in all skin types, including ethnic.
The appearance of the treated area immediately after a laser procedure will vary from individual to individual depending on many things, some being the extent of treatment, skin type, denseness and coarseness of hair, and hair colour. Immediate post-treatment effects are minimal, including redness and swelling around the hair follicle, This in fact, is a desired clinical result, and indicates the follicle has responded well to treatment. It is a rapid, non-invasive procedure that usually has no client down-time .
Human hair cycles through three stages:
The anagen phase, or growth phase, is when all new hair growth occurs. During the anagen phase, hair grows at its normal rate (an average of one-half inch per month), and 90% of the hairs on your head will be in the anagen phase at any given time. Each specific hair can be in the anagen phase for an average of three to five years, but it can last as long as ten years in some cases.
The catagen phase, a transitional phase that follows the anagen phase, signaling the end of the growth phase. During the catagen phase, the hair follicle contracts and detaches from the dermal papilla (where it gets its nutrients). The hair bulb disappears and the root end of the hair forms a rounded club. Less than 1% of the hair will be in the catagen phase at any given time, and this phase usually lasts one to two weeks.
The telogen phase is also known as the resting phase and is the last phase in the hair's growth cycle. The telogen phase lasts until the fully grown hair is shed. Hair that is in the telogen phase is usually shed during this phase, or after the start of the next anagen phase when it gets pushed out of the follicle.
