MONDAY, April 11 (HealthDay News) -- A new study of middle-aged black women finds that almost 30 percent suffer from baldness and scarring in the center of their scalps, possibly because braids and weaves pull their hair too tight.
The study doesn't prove that black women's choices about hair grooming play a major role in whether they lose significant amounts of hair. However, the findings are enough to suggest that black women need to be cautious, said study lead author Dr. Angela Kyei, a dermatologist at the Cleveland Clinic.
"You have to stop and think about what you're doing with your hair, and you have to look at your children's hair," Kyei said. "African Americans begin putting relaxers and chemicals in their children's hair early. You have to start thinking about what might happen later on."
Baldness in the middle of the scalp is quite common among black women, Kyei said, but there hasn't been much research into what causes it.
In the past, dermatologists thought that hot combs or hair oils were the cause of the hair loss. Another suspect was the chemicals that black women use to relax their hair, turning it from curly to straight.
But, dermatologist Dr. Jerry Shapiro, a clinical professor of dermatology at the University of British Columbia who specializes in hair problems, said, "There are many women who use relaxers who don't have this problem."
One thing is clear about the baldness, however: "Once you get it, it's permanent," Kyei said, and the hair doesn't come back. "That's why a lot of African Americans wear wigs or put something on their scalp to hide their hair."
In the new study, Cleveland Clinic researchers examined the hair of 326 black women who were approached at churches and a health fair in Cleveland. The women answered questions about their hair and their health.
