Twins Studies Find Several New Predictors for Female and Male Hair Loss
For Release: 09/21/2011
"Never before has the role of some of these contributors to hair loss been documented," said Bahman Guyuron, MD, ASPS Member Surgeon and study co-author. "While genetics remain a strong predictor of some types of hair loss, introducing certain stressful or unhealthy factors into a person's life can result in more hair loss."
One study examined 84 female identical twins and found the strongest predictor of female hair loss was marital status. Those who were divorced or widowed exhibited more hair loss than married women. In addition, a large weekly consumption of alcohol led to higher levels of female hair loss along the front of the head. Heavy smoking was a significant contributor to female hair loss in the temple area. However, women who drank moderately - two alcoholic beverages a week - experienced significantly less temporal hair loss than their twin.
"Identical twins are genetically programmed to experience similar patterns of aging and hair loss," said Dr. Guyuron. "If one twin loses more hair than the other, it is related to external factors."
A second study looked at 66 male identical twins and found that while genetics was the strongest predictor of male hair loss along the front of the head, smoking, heavy sun exposure and a history of dandruff were also contributors. In addition, medical conditions like hypertension, a lack of regular exercise, and elevated testosterone levels contributed to increased rates of hair loss in men.
"There is as much interest in preventing and treating hair loss, as there is in finding ways to turn back the clock," said Dr. Guyuron. "Many women, and men, deeply suffer from hair loss. Discovering the controllable factors that contribute to hair loss will help us to prevent it more successfully and develop better means to manage this troubling condition."
The study, "The Relative Contribution of Endogenous and Exogenous Factors to Male Alopecia: A Study of 66 Genetically Identical Males," is being presented Saturday, September 24, 2:50 p.m., and the study, "The Relative Contribution of Endogenous and Exogenous Factors to Female Alopecia: A Study of 84 Genetically Identical Females," is being presented Sunday, September 25, 11:05 a.m., at the Colorado Convention Center in Denver.
