the progression of the hair growth cycle.

- Catagen is a period of regression. By the fifth year the hair
follicle enters a resting period where gets ready to shed. This phase
normally lasts between two to four weeks.
- Telogen is the stage where a hair follicle reaches the end
of its life and falls out. While people on average shed fifty to one
hundred of these hairs a day, each hair follicle will renew itself and
enter a new growth cycle. This phase can last up to four months. Not
more than ten percent of follicles are in resting phase at any given
New Hair Growth Cycle
All hairs are not visible on the surface of the skin at the same time.
The varying stages in the growth cycle determine how hair grows. Following
the first three stages of the hair growth cycle, the hair is shed, and
the follicle moves into a dormant period. When the dormant period is over
the cells that produce hair begin a new cycle.
A healthy head of hair contains approximately one hundred thousand hairs
that should grow at the rate of about half an inch per month. When the
hair loss cycle is interrupted hair loss may occur.
