Each individual hair is formed inside a hair bulb deep in a hair follicle
• The hair grows about 0.3 to 0.4 mm each day (1cm per month)
• A single hair lives approximately five or six years
• The hair spontaneously falls out
• The follicle rests for a little while, and then starts to produce yet another new hair
1- Anagen – the growing phase
2 - Catagen– the intermediate phase
3 - Telogen - the shedding phase
If hair is healthy:
1- 85% to 90% of hair is in its Anagen phase
2 - 1% is in Catagen phase
3 - 14% is in Telogen phase
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.
Hair loss is usually triggered by a combination of hormonal activity and heredity, which together cause the hair follicles in the 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.
50% of a man’s hair Is gone before It becomes noticeable.
For men in their 20s, there is an approximate 20% occurrence of male pattern baldness, and men in their 30s face a 30% rate of occurrence. This is a general statistic that can be applied to men all the way up to their 90s.
The average woman is born with about 100,000 hair follicles on her head, which she keeps for the rest of her life.
On average most women lose between 50 and 100 hairs per day and if hair is healthy, it will grow back on its own.
If you are one of the millions of women who experiences hereditary hair loss, you may be losing 150 hairs or more a day-hair that doesn’t grow back as thick and healthy as it once was. Indicators of this include; more hair on your brush, in your sink, or in the shower drain.
Whilst there are many conditions, diseases, and hair care practices that can contribute to, or result in female thinning hair and excessive hair loss, hereditary hair loss accounts for the majority of hair loss.
Women’s hair loss is different from men’s because it’s more diffused.
Hair loss can also be a symptom of stress, pregnancy, and as a result of certain medications.
