Gray hair has more continuous medullation and a higher medullary diameter than black hair.
research Central centrifugal cicatricial alopecia
CCCA is a scarring hair loss condition mainly in African descent women, possibly caused by genetics and hairstyling, treated with gentle hair care and medications.
research Central Centrifugal Cicatricial Alopecia (CCCA)
CCCA is a common hair loss condition in African American women, often inherited and influenced by hairstyling, with unique scalp features detectable by special tools.
research A 40-Year-Old Woman of African Descent with the Central Scalp Hair Loss
