Interesting facts about hair

Hair growth in phases

Understanding how hair grows helps us understand how to keep hair from growing. Each hair is contained in a pilosebaceous unit, which consists of a hair shaft, hair follicle, sebaceous gland, and erector pili muscle.
Hair growth and shedding is a continuous cycle through 3 phases. The anagen phase is the active growth phase of hair follicles. The cells in the root of the hair are dividing rapidly, adding to the hair shaft.
The catagen phase is a short transition stage that occurs at the end of the anagen phase. It signals the end of the active growth of a hair. This phase lasts for about 2-3 weeks.
The telogen phase is the resting phase of the hair follicle. At any given time, 10%-15% of all hairs are in the telogen phase. This phase lasts for about 100 days for hairs on the scalp and much longer for hairs on the eyebrow, eyelash, arm and leg.
About 25-100 telogen hairs are shed normally each day.

Cosmetic hair removal can be quick and easy or time-consuming and somewhat uncomfortable. It can be costly or inexpensive. But, for just about anyone who so desires, there's a way to get rid of the hair you don't want.
There are several hair removal methods, but none is 100% permanent. With most of these methods, the hair eventually grows back. Remember that for any product applied to the skin, be it wax, depilatory, or prescription cream, first test the product on a small area to be sure you do not have an allergic reaction or display hypersensitivity and, of course, follow the package directions.
Let's clears up a myth: no method of hair removal has ever been shown to result in an increase in hair growth. Shaven hairs sometimes appear thicker than hair that has been allowed to grow, and thus, with time, have a weakened shaft and softer ends, but they aren't actually any thicker.
