Good news for men who suffer from male pattern baldness. A new study has uncovered yet another clue into the cause of the condition, and a cure may not be too far away.


Last year, I told you about a study from researchers at the University of Pennsylvania that was getting to the root of male pattern baldness. In this study, researchers found that bald areas of the head make fewer progenitor cells, the cells that create the hair follicle stem, than areas of the head where hair grows normally.  


Now, a new study from the same team has taken the research even further. This study, published in the journal Science Translational Medicine and released March 21, evaluated men with male pattern baldness and found that bald areas of the scalp had higher levels of a protein called prostaglandin D2 than the hairier parts. When this protein was applied to human hair follicles in a lab dish, the hair stopped growing.


Dr. George Cotsarelis, chairman of dermatology at the University of Pennsylvania and the lead researcher for the study, noted that these new findings may lead to a treatment for baldness that involves suppressing the prostaglandin D2 to make it to stop or even reverse hair loss.
