Laser Hair removal Growth Cycle

Laser Hair removal Growth Cycle

Laser hair removal growth cycle is the critical factor for permanent hair reduction. There are 3 period in the hair growth cycle: Anagen, Catagen and Telogen. Only in the Anagen period, hair could be removed by diode laser machines. This cycle is where the hair is visible on the surface of the skin. The laser will grab ahold of the live hair and move through it into the hair follicle making it the best time for successful laser hair removal. In the stage Catagen or Telogen, laser hair removal treatment is not working well.

Anagen :

The first stage of hair growth cycle is Anagen. In this stage hair is visible above the skin and is still attached to the papilla. This hair growth Anagen phase is ideal for laser hair removal because since it is still attached to the papilla the laser can attack the papilla and prevent any new growth. Stage anagen usually keeps around three weeks(Same situation in the face and body)

Catagen : 

This stage will last about 2 days, it is a short period. Catagen stage is not exactly a good time for permanent hair removal because during this stage that the hair begins to shed. You can still get the treatment as the follicle will produce another hair. This shedding is not the same as after the treatment.

Telogen : 

Telogen is the last stage of hair growth. In this period, laser hair removal treatment cannot be done. The hair is not growing and developing. In Telogen stage, the hair is no longer attached to the papilla. This stage laser will not work because there is little melanin and could not be absorbed.

Of course we do not and can not make it very clearly which hair in which stage. So that is why permanent laser hair removal often needs 4 to 6 times.
