Central Hair Loss in African American Women: Incidence and Potential Risk Factors

In a study of 529 African American women, researchers sought to determine the frequency and potential causes of central scalp hair loss. They found that 5.6% of subjects experienced extensive central scalp hair loss, with the only significant association being a personal history of tinea capitis. The study used a central scalp photographic scale and questionnaire to assess hair loss patterns and did not find a clear link to the use of relaxers, hot combs, seborrheic dermatitis, reactions to hair care products, bacterial infections, or male pattern hair loss in fathers. The study had limitations, including the lack of scalp biopsy correlation and the need for more detailed information on hair care practices. The findings suggest that clinicians should focus on identifying and treating inflammatory conditions early to prevent this type of hair loss.
