March 21, 2012 (San Diego) -- If you are a woman of color, you may already know: Your hair can be an issue.
No, it's not your imagination or vanity working overtime, says Amy McMichael, MD, professor and interim chair of dermatology at Wake Forest Baptist Medical Center.
"There is some sort of innate fragility," McMichael says, referring to the hair of African-American women.
That fragility can result in breakage and hair loss, what doctors call alopecia, she says. She presented an update on hair loss and other issues in people of color at the annual meeting of the American Academy of Dermatology held here.
There is much you can do, however, to boost your hair health, she says. Here, she shares her healthy hair tips with WebMD.
1. Hair Loss Is Common in African-American Women
Hair loss is a common reason that women of color see a dermatologist, says McMichael.
She and her colleagues discovered that when they looked at a national database, the National Ambulatory Medical Care Survey, to find the top reasons for visits to dermatologists by African-Americans.
"Alopecia was right up there in the top 10," she says. It was reason No. 7 to see a dermatologist.
2. Kinds of Hair Loss That Affect African-American Women
By looking at where the hair loss occurs, doctors can sometimes decide how it occurs and what kind of hair loss it is.
For instance, braiding too tightly can lead to alopecia, McMichael says. "It is usually a clinical diagnosis made by physical exam," she says. Hair loss usually occurs on the front, temples, and back of the scalp.
Your doctor may take a biopsy to help get the diagnosis correct.
Another type of hair loss is called CCCA -- short for central centrifugal cicatricial alopecia. It can cause scarring on the front and crown of the scalp, McMichael says. It can be inflamed and the scars can be severe, she says.
The exact cause of CCCA is not known, but some experts believe it may be linked with long-term use of chemical hair treatments, such as chemical hair straighteners.
3. African-American Hair Is Unique
Dermatologists have found that the hair shaft of African-American women is structurally different than the hair shaft of women of other races, McMichael says.
The hair shaft is flatter, she says, compared to that of Asian or white women.
In another study, McMichael surveyed 30 African-American women and 30 white women. While 60% of African-American women said their hair was too dry, 67% of Caucasian women said their hair had normal moisture.
That dryness can result in breakage, she says. African-American women are more than three times as likely as white women to have hair shaft breakage, she says.
Often, she says, no underlying medical reason is found. "This is very disturbing to patients, I find. They wish there was some underlying disease and they could take a pill."
