Hair Growth Cycles

Hair growth cycles have a direct effect on how Laser hair removal works. One of the most popular questions is that why laser hair removal is not 100% permanent and the answer is in the way that hair growth in our body. First, new hair will start growing at the root and will continue to grow until it reaches its maximum length. It will then shed and finally be replaced by a new hair and the cycle begins all over again. In total, there are three main phases in a hair’s life cycle:

First, new hair will start growing at the root and will continue to grow until it reaches its maximum length. It will then shed and finally be replaced by a new hair and the cycle begins all over again. In total, there are three main phases in a hair’s life cycle:

Anagen Phase (the active growth phase):

This is the active phase of hair growth. Hair has the most melanin and that’s why it is the best phase for laser hair removal. This phase will last for several weeks.

Catagen Phase (transitional period):
 This is the end of the growth phase. The hair stops growing and the hair follicle separate from the base. This phase will last for 2 weeks.

Telogen Phase (shedding phase):

This is the resting phase of hair growth. The old hair is pushed out by the new hair, and thus the cycle begins. This phase will last a few months and Anagen Phase begins again.

On average at any given time, 85-90% of hair is in the Anagen phase, 1% in the Catagen phase and 10 to 15% in the Telogen phase. The laser can only target the hair in the Anagen stage and while not all of the hair is in the Anagen phase, that’s why we need different sessions for laser hair removal treatment and it’s not 100% reduction. At least Six to Nine laser hair removal sessions spread four to six weeks apart are generally required to achieve the results. However, the number of treatments to have the maximum result depends on the body and part of the treatment would be more!!
