How does hair grow?
Hair loss is a problem that can occur at any time and to anyone. Hair goes through three different growth stages:
- The first stage: Anagen: is where the hair grows and lengthens from the follicles. This process takes 2-5 years on average.
- The second stage: Catagen: is where the hair starts to get weak and separate from the follicles. This process takes about 2 weeks on average.
- The third stage: Telogen: is where the hair breaks from the follicles and falls. This process takes 3 weeks on average.
Here are some facts about hair that you may not know:
According to research by Dr. Iman Al Haj, who received her board certification in General Surgery from the United Kingdom Medical Board and is a hair transplant specialist in Qatar, hair is made up of a protein called keratin, that is produced in hair follicles in the outer layer of the skin.
As the follicles produce new hair cells, old cells are being pushed out through the surface of the skin at a rate of about six inches a year.
The hair you see is actually a string of dead keratin cells. The average adult head has about 100,000 to 150,000 hairs, and loses up to 100 of them a day.
Finding a few stray hairs on your hairbrush is not necessarily a cause for alarm. At any one time, about 90% of the hair on a person’s scalp is growing.
Each follicle has its own life cycle that can be influenced by age, disease, and a wide variety of other factors.
