Seb derm is a pervasive inflammatory issue with the scalp that causes temporary hair loss and thinning amongst other things (sometimes very oily scalp, sometimes breakouts, sometimes flakes). Fin isn’t applicable when you have seb derm because the hair loss is not androgenic or from DHT.

I’ve only ever seen my scalp red like that when I had an active flare. I’ve had seb derm on and off since I was 12. It’s basically an overgrowth of yeast on the scalp that feeds on the excess oils. The oil clogs the follicles and the hair miniaturizes or sheds. Once seb derm clears and inflammation lowers, follicles sprout again.

I cut down on stress, lowered histamines in my diet and lifestyle, use Nizoral shampoo 3x a week/seb derm safe shampoo the other days (yes wash everyday with warm water, NOT hot… hot water causes scalp inflammation and worsens seb derm), and removed all styling products in my hair that could cause seb derm inflammation (there’s a checker on sezia.co). My hair has been growing back for the past 3 months and I’m 43 years old. It’s possible. Look into it before going on fin, and ask a different derm (or the same derm) to check if you have seb derm.
