How does the hair grow? - QR 678

The hair grows in three phases:
The Anagen phase which is the active hair growth phase and lasts from two to eight years. Catagen phase which is the regression phase in which the hair transitions to shedding and this phase lasts for about 10 days. Telogen phase is the resting phase of the hair after which the hair detaches itself from the scalp and the follicles in rest for about three months before the hair growth cycle starts again.
