Trying to find a cure for baldness has been about as easy as trying to find a needle in a haystack. But this may all be about to change because scientists have identified a protein called PGD2 in the scalps of men with male pattern baldness. Researchers say if they can find a way to keep this protein from attaching to hair follicle receptors, they could prevent baldness.
The study, published in the Science Translational Medicine journal, examined samples from 17 men with hair loss and found that their bald scalp tissue had three times the levels of PGD2 compared with the hair-covered tissue from the same individual. PGD2 causes baldness through a receptor called GPR44. The hope is to develop a way to block this receptor.
Male pattern baldness affects 8 out of 10 men under the age of 70, and causes hair follicles to shrink and create microscopic hairs, which grow for shorter time periods than normal follicles.
The scientists in the study wrote that this discovery could very well lead to new treatments for the most common cause of hair loss in men.
