The Nation : Hormone Tied to Baldness

Scientists said they have found a molecular “missing link” confirming that the balding condition that shines the scalps of millions of men is tied to excessive activity of male hormones. The University of Miami team reported that oil glands in scalps struck by male-pattern baldness have molecules, called receptors, with 50% to 100% greater capacity for binding the ingredients of the male hormone testosterone. The receptor process short-circuits hair growth but how this happens is not yet clear, said Dr. Marty Sawaya of the school’s department of dermatology. It is uncertain whether the finding will lead to a drug to combat baldness, she said.
