Hair growth & its anatomy

Hair is a simple structure made of a protein called keratin. A hair follicle is an important part that anchors each hair into the skin & a hair bulb forms the base of the hair follicle. So, in the hair bulb, living cells will divide and grow to build the hair shaft. 

The cells in the hair bulb are nourished by blood vessels and hormones are regulated to modify hair growth and structure at different phases of life. Sebaceous glands present near the hair follicles produce oil, which nourishes the hair and skin.

Hair growth cycles consist of three phases – anagen (growth phase), catagen (transitional phase) & telogen (resting phase). Then hair growth stops, and the old hair detaches from the hair follicle. 

This new hair begins the growth phase, pushing the old hair out. Hair growth rates vary in different people, on average growth rate is around one-half inch per month. 

Hair color is decided by melanin-producing pigment cells in the hair follicle. With aging, as pigment cells die hair turns grey.

What causes alopecia areata?

Alopecia areata is an autoimmune disorder where one’s own immune system generates a response against healthy cells by mistaking them as foreign invaders. 

Generally, our immune system acts as a defense force by acting against harmful bacteria, viruses & other microorganisms. So, in this clinical condition, the immune system destroys the hair follicles which are responsible for hair growth. 

As a result, these hair follicles get smaller, stopping hair production and leading to hair loss. In some cases, hair loss may occur in eyelashes, eyebrows, face, or other parts of the body. However, it occurs in individuals with a family history of alopecia areata or other similar autoimmune conditions.
