The root cause of baldness may have been found by scientists who have identified one chemical that causes the condition. Researchers say this protein is key to controlling when hair follicles cells divide - and when they die.
The discovery could help also treat the healing of wounds, said researchers at the University of California, Riverside. Hair follicles are the source of stem cells, which help promote wound healing.
The scientists compared stem cells to blank tiles in Scrabble. Unlike most cells in the body that have a specific function and cannot change, stem cells can turn into other types of cells. This adaptability makes them useful for repairing damaged tissues and organs.
