Wow with so many HT doctors and HT Advisors i'm surprised no one has shed some knowledge on this.
Tom: Meds don't have anything to do with oily scalp.
But yeah, you're right, oily scalp is a cause of stupid DHT hormone.
something interesting is the people who are not balding. Their scalp is never oily.. (i know cuz i've ran my fingers through their hairs, feeling their scalp) and come to think of it, i don't remember my scalp being oily back in the day when i had shit loads of hair.
