A cousin of a molecule that stimulates eyelash growth may stop hair growth on the scalp
Just because a man is bald doesn’t mean there’s nothing going on in his scalp. A molecule found in the scalps of bald men may offer clues about how male pattern baldness arises and what to do about it.
Men with male pattern baldness have higher levels of a molecule called prostaglandin D2 in the bald parts of their scalps than in parts still covered in hair, a new study shows.
