What is the hair growth cycle and how does hair growth work? |
|
Under normal circumstances hair growth in each hair follicle occurs in a cycle. There are three main phases of the hair growth cycle: anagen, catagen and telogen. Anagen (active) is the growing phase or when the hair fiber is produced. During anagen, the hair contains an abundance of melanin, the pigment which gives your hair its color. This is the phase during which laser hair removal treatment is most effective. Catagen (club hair) is the period of controlled regression of the hair follicle. This phase is when the lower part of the hair stops growing, but does not shed. It will be difficult for permanence to be achieved when the hair is in the catagen growth cycle.
Telogen (tired) is the last of the hair growth cycle. In this resting phase, the old hair falls out in preparation for the development of a new anagen hair. Permanence cannot be achieved
