Hair grooming practices, such as braids and weaves, as well as
inflammation in the form of bacterial infection, may be contributing to the
development of scarring hair loss in African American women, according
to a report posted online that will appear in the August print issue of Archives
of Dermatology, one of the JAMA/Archives journals.
"Central centrifugal
cicatricial alopecia (CCCA) is a term coined by the North American Hair
Research Society to describe a scarring hair loss, centered on the
vertex of the scalp, that spreads peripherally," the authors write as
background information in the article. "It is thought to be the most
common pattern of scarring hair loss seen in African American women, yet so
little is known about its true prevalence among them."
Angela Kyei, M.D., M.P.H., and
colleagues at the Cleveland Clinic, Cleveland, Ohio, conducted a study to
investigate medical and environmental risk factors for CCCA. A total of 326
African American women answered questionnaires at two African American churches
and a health fair in Cleveland. The researchers analyzed data on the study
participants' demographics, family and medical history, hormonally driven
conditions, and methods of hair grooming.
The study results suggest there is a
high prevalence of central hair loss among African American women.
"Advanced central hair loss with clinical signs of scarring was seen in 59
percent of these respondents and was interpreted as clinically consistent with
CCCA," the authors report. "Diabetes mellitus type 2 was
significantly higher in those with CCCA, as were bacterial scalp infections and
hair styles associated with traction (e.g., from braids and weaves)."
The increase in type 2 diabetes
among women with CCCA is in line with recent theory that cicatricial alopecia
may be a manifestation of metabolic dysregulation.
"The results of this study
suggest that hair grooming practices that cause traction, such as weaves
and braids, may be contributing to the development of CCCA because these styles
are more commonly used in those with the most severe central hair loss
to increase hair style versatility while camouflaging hair loss,"
the authors write. "Given the fact that many African American women pay
hundreds of dollars to have their hair braided and weaved, they often maintain
these hair styles for weeks to months at a time to justify the money spent. The
resulting prolonged traction can produce chronic folliculitis, which can
eventually lead to scarring."
