Male pattern baldness is linked to an increased risk of coronary heart disease, but only if it's on the top/crown of the head, rather than at the front, finds an analysis of published evidence in the online journal BMJ Open.

The first animal model of recent human evolution reveals that a single mutation produced several traits common in East Asian peoples, from thicker hair to denser sweat glands, an international team of researchers reports.
Your hair -- or lack of hair -- is the result of a lifelong tug-of-war between activators that wake up, and inhibitors that calm, stem cells in every hair follicle on your body, according to Cheng-Ming Chuong, M.D., Ph.D., of the University of Southern California (USC).
New research, to be published in the Journal of Clinical Psychiatry, finds that men who developed persistent sexual side effects while on finasteride (Propecia), a drug commonly used for male pattern hair loss, have a high prevalence of depressive symptoms and suicidal thoughts.
A hair-raising trick may lead to better hair transplants. Engineered hair follicles patched into skin can be coaxed to connect to surrounding tissue and to grow hair in an organized way, a study in mice finds. Unlike current hair transplant methods, which simply move existing hair follicles from one area of the scalp to another to cover a bald region, the approach would spur the creation of new hair follicles from existing cells.
A state appeals court in San Francisco has upheld $40 million in damages to 150,000 Californians who sued the manufacturers of the hair-regrowth product Avacor over advertising claims that it was effective in regrowing hair. An Alameda County jury and judge found the advertising claims false in 2010 and ordered refunds on purchases in California from 2000 through April 20, 2007, a sum reduced by 22.5 percent to reflect the customer-satisfaction rate found in a U.S. Food and Drug Administration survey.
