Hair Loss Types

Androgenic alopecia and traumatic alopecia are the most common causes of hair loss in women.

Androgenic alopecia
Hereditary hair thinning occurs in both men and women.
It is the most common form of alopecia in women.
It can begin as early as in the 20s.
By age 40, 40% of these women have noticeable hair thinning due to this condition.
By age 50, 50% of them have severe signs of hair loss.
When this type of hair loss occurs, women usually do not develop true baldness in the patterns that occur in men, the areas affected are in the temples and the crown of the head, while the front hairline is usually preserved.

Traumatic alopecia
Scarring in the scalp area which causes hair loss. This form of hair loss frequently occurs in African-American women.

Traumatic alopecia is divided into three categories: traction, chemical and follicular alopecia.

Traction alopecia
Hair loss associated with persistent use of tight braids, hair rollers, weaves, twist, locks, or cornrows.

The first sign of traction alopecia is thinning above the ears and the forehead. This hair loss is often seen in young girls

Partial or complete regrowth of hair can follow, but permanent loss of hair can occur when the roots of the hairs are severely damaged.

Chemical alopecia
Damage to the scalp and hair shaft caused by commercial relaxer products.
It will resemble hair thinning resulting from hereditary causes, but it will also include scarring of the scalp, which could irreversibly damage the hair follicles.

Follicular alopecia
Gradual destruction of hair follicles that occur when the excessive use of pomades with a hot comb or iron.

Thinning usually begins at the crown and then spreads evenly throughout the head. It is an irreversible

Alopecia Areata
Alopecia areata is an autoimmune condition where the hair follicles are attacked by a person’s own immune system, resulting in the arrest of the hair growth stage. Alopecia areata usually starts with one or more small balding patches on the scalp and can progress to total hair loss.
