Factors that determine hair loss

Factors that determine hair loss

Over the past several years, dermatologists have made some interesting statistical findings that explain the pattern of hair loss. Curiously enough, the phenomenon of falling hair is provenly related to the rate of hair growth, length of the hair, age and even the color of hair.

It is normal to shed from 50 to 80 strands of hair a day. It is normal for each of those hair to be replaced by the hard-working follicles. On any given day, about 90% hair are in the growing stage. This period lasts for about 1000 days. 10% hair are in the resting stage which lasts for about 100 days before the follicles eventually grow out.

Interestingly, the fall-out occurs mostly in the morning. This fact remains unexplained.

The length of hair is an important factor in hair loss. The four-inch long hair, loses on an average 87 hairs a day; the 12-inch long hair loses about 26 hairs a day; and 20-inch plus long hair loses as little as 16 hairs a day on an average. The longer the hair, the less is the hair loss.

Hair grows on an average of 6 inches a year, and shortfall in the normal hair growth is accompanied with a hair loss too. Apart from the day-to-day loss, we shed more than usual hair during six periods of our life; from birth to age three; at ten, at twenty-two, around the age of twenty-six, at thirty-six and around fifty-four. This happens due to hormonal changes that occur in our bodies during these periods of our lives.

The maximum hair growth on women occurs between the age of fifteen to thirty.
