Women with androgenetic alopecia have normal levels of most blood steroids and binding proteins, but higher dehydroepiandrosterone. Some also have low "sex hormone-binding globulin" and "corticosteroide-binding globulin" capacity, and high "free androgen index" and "free cortisol index". Diane treatment can normalize these levels and improve hair conditions.
