Hair growth cycles has three distinct growth phases: 1) Active growth phase, 2) Regressive phase, 3) Resting phase.
Medical research has conclusively shown that hair growth cycles differ on various parts of the body. The laser most effectively disables hair that is in the 1)  active growth (anagen) phase. Below, we take a look at the various hair growth cycle and the effects of laser hair removal.

1) Active growth phase (Anagen phase)

It is ONLY during this stage that we can permanently disable hair growth. It is the BEST effects during this stage for laser hair removal. The Anagen phase will lasts up to several years. At any given time, the majority (85%) of our body hair is in this phase. During anagen, the hair follicle is directly connected to the blood vessels and the hair has an abundance of melanin

The laser target is in the melanin of the hair. There are the best effectiveness of laser hair removal because of an abundance of melanin during active growth phase. Laser will cut off the blood supply to hairs, All the hair in the target area will be affected during the laser procedure but only the hair follicles in the Anagen phase will be permanently disabled. Laser hair removal treatments are done over time because there are not 100% of the hairs in the Anagen phase, but but levels approximating 80 to 90% permanent is possible.

2) Regressive phase (Catagen phase)

Hairs cannot be permanently disabled while the hair can be destroyed. The hair is not visible and capable of absorbing the laser light and therefore cannot be destroyed. Hairs is no longer connected to the blood supply. The Catagen phase will lasts about two weeks, during which the hair stops growing but is not yet shed. About 3 - 4% of our body hair is in this phase at any given time.

3) Resting phase (Telogen phase)
Hair is no longer connected to anything and it is preparing to fall out. The hair is not visible and capable of absorbing the laser light and therefore cannot be destroyed.

The Telogen phase will lasts 5 - 6 weeks, at the end of which the hair falls out and a new hair begins to form. Approximately 10-13% of our body hair is in this phase at any one time.
