Scientists discovered the Biological Clue to Male Baldness

Scientists discovered the biological clue to male baldness. It increased the chances of a treatment to stop or even reverse hair-loss. They found that most men go bald in middle age. About 80 percent of men have some hair loss by the age of 70.The male sex hormone testosterone as well as genetic factors cause the hair follicles to shrink, which leads to the appearance of baldness. A key protein’s presence (called prostaglandin D syntahse) is increased in the cells of hair follicles which can be located in bald patches on the scalp, but not in hairy areas.

Scientists carried out their experiments on two groups of mice. Mice who were given high levels of the protein became completely bald. While the other group showed no signs of baldness. Scientists concluded that the inhibition of hair growth is triggered when the protein gets itself attached to a receptor on the cells of hair follicles.

Scientists have already identified drugs that target this pathway. There is potential for developing a treatment that can be applied to the scalp to prevent baldness and help in re-growing hair.
