How does hair growth work?
The normal hair growth cycle involves three main phases: Anagen (active) is the growing phase, when the hair fiber is produced. During this stage, hair is rich in melanin, the pigment which gives hair its color. Laser hair removal treatment is most effective during this period. Catagen (club hair) is the period of controlled regression of the hair follicle. The lower part of the hair stops growing, but does not shed, and the follicle is reabsorbed. At this stage, permenent hair removal is difficult to achieve. Telogen (tired) is the last stage. The old hair falls out in preparation for the development of a new anagen hair. Permanence cannot be achieved when the hair is in this resting stage.
