Laser hair removal works by using laser to damage the hair follicles, so as to slow down the process of further growth, leaving a silky smooth feel, even on sensitive skin. The laser works by disabling hair in the active growth phase at the time of treatment.
Laser light is fast gaining preference over traditional methods, such as electrolysis, shaving and waxing because it is so safe, effective, fast-acting, and convenient and allows the treatment of large areas at a time. No need to take any time off from your daily activities either!

How hair growth cycles affect laser hair removal

Hair growth is affected by several factors-age, sex, weight, metabolism, hormones, genes, ethnicity, medications, body location and seasonality. At any one time, the hairs from various parts of the body are at one of 3 cyclic phases (Anagen, Catagen or Telogen). This is why all the body hair does not fall out at the same time and takes months to grow back.

Anagen

80-85% of hair is in the active growth phase, Anagen, at any given time. It can last for several years and the hair has abundant melanin during this time.

Catagen

Laser Hair RemovalThe Catagen or transition / regressive phase lasts only about 2 – 4 weeks. In this phase, the hair stops growing but is not yet shed. About 3-4 % of body hair is in this phase.

Telogen

Lasting weeks to months, the Telogen or resting phase is when hair falls out and new hair begins to form. At least 10-15% of body hair is always in this phase.

Catagen or Telogen-phase hair may not be fully destroyed during treatment as the hair follicle is actually no longer attached to the root. Anagen phase hair is considered ideal for laser removal. As 80 – 85% of hair follicles are in the Anagen phase at the same time, multiple treatments are usually needed to remove all the hair from each area. Depending on the body area being treated, most people require 6 treatments, spaced 4-6 weeks apart.
