What is the growth cycle of hair?

ANSWER

Normally, hair goes through a regular growth cycle. During the anagen phase, which lasts 2-6 years or longer, the hair grows. During the telogen phase, which lasts about 3 months, the hair rests. At the end of the telogen phase, the hair falls out and is replaced by new hair.
