What are the 3 phases of hair growth?
Anagen – is the active growth phase. During this phase, the hair contains an abundance of melanin
Catagen – is the regression phase. During this phase the lower part of the hair stops growing.
Telogen- is the resting phase. During this phase the old hair falls out with the preparation for the development of the new hair.The laser works when the hair is in the anagen phase.
