Basic facts about your hair

  • The average scalp is covered with 100,000 hair follicles.

  • Most people lose between 50-100 hairs a day - but a consistent loss of 150 hairs or more a day is considered significant hair loss.

What causes
hair loss in men?

Although there are several causes of hair loss, male pattern baldness (also referred to as androgenetic alopecia or hereditary hair loss) accounts for about 95% of hair loss in men. It is usually triggered by a combination of hormonal activity and heredity, which together cause the hair follicles in your scalp to shrink. Over time, the progressive shrinking of certain scalp follicles leads to a shortening of the hair's growing cycle. Hair becomes thinner and shorter, until there is no growth at all.
