CCCA affects approximately 5% of Black women. It is a scarring (cicatricial) form of hair loss that starts at the vertex scalp and spreads outwards over time. It was initially thought to be due to hot comb and relaxer use, but increasing evidence suggests this runs in families. It has also been found in association with uterine fibroids and diabetes.

Traction alopecia is initially reversible, but can become irreversible. It presents with thinning at the frontal hairline (or at the crown in locs, for example), often without symptoms. However, at times redness, pain, itching and pus-bumps can be present. It is due to high tension styling, however there can be a >10 year delay in the style use and the hair loss.

This is common in all hair types and should not be overlooked in curly hair textures. This tends to run in families. The crown of the scalp will often have fine, straighter hairs than other parts of the scalp. This typically does not have symptoms.

Trichorrhexis nodosa is a term used for damage of the hair shaft resulting in breakage. Although there is a hereditary form, often this is due to hair care practices. Heat or chemicals may cause or exacerbate damage. If hair is breaking (as opposed to falling out from the root) with minimal manipulation, consider this condition.
