Weaves and braids may contribute to a type of permanent hair loss that appears to be common among black women, a new study has found.
More than one-quarter of the 326 black women who participated in the study had hair loss on the top of their scalp, and of those women, 59 percent had signs of central centrifugal cicatricial alopecia, or CCCA, a poorly understood form of baldness that begins at the crown of the head and leads to scarring.
