The Hair Growth Process

A new hair grows when a group of cells at the base of the hair follicle multiply rapidly. Older cells move upward and form the hair shaft. The hair growth phase typically lasts 2 to 6 years.

Eventually, the hair stops growing. The hair follicle then enters a resting phase. After this, the hair follicle reenters the growth phase. The older hair is shed and replaced by a new one.

What Causes Hair Loss?

The most common cause of hair loss in men and women in androgenetic alopecia (AGA). Heredity, hormones, and age all play a part in this condition. In AGA, the hair follicle shrinks.

Each hair growth cycle produce a shorter, finer, much-less-visible hair. In time, a few follicles will become incapable of producing visible hair.
