Hello dr.Rasmman your site is really informative.Thank you for all this information.I have a question to ask.Is sebum rich in dht and testosterone? I mean if you don’t wash your hair and have an oily scalp,can this accelerate male pattern baldness allot sooner than it would normally start?
I’ve written about this before. And as I said then, most of the claims of sebum containing high concentrations of DHT (thus leading to hair loss) seem to be coming from companies that sell shampoos. These claims are just not supported by today’s science.
Taking finasteride does seem to reduce the amount of sebum, but the connection between sebum and hair loss (because it contains DHT) has no basis.
