HealthExtra: Smoking’s hair-raising impact

Smokers may run the risk of losing their hair, say Taiwanese researchers. Looking at 740 men, average age 65, investigators found that cigarette smoking played an important role in developing moderate or severe hair loss when men smoked 20 or more cigarettes a day. Authors of the study, published in Archives of Dermatology, suggest that smoking may destroy hair follicles, interfere with blood and hormone circulation in the scalp or increase estrogen production.
