Q: I was told that if men have a lot of testosterone that that’s when they lose hair. Is this true? — Y.B., Lake Forest, Illinois

A: Although androgenetic hair loss is dependent upon normal levels of testosterone, it is not due to increased testosterone. It is caused by a sensitivity of the follicles to normal levels of testosterone.

So someone that is bald doesn’t have extra levels of male hormones and is not necessarily over-sexed.
