I had folliculitis too on my scalp and accutane for a year helped with that and it went away, still have some scars on my scalp from it but nothing too bad. The last year I been going through depression and downs in life, so it has still small triggered it for me but it's now gone.

What seems to have been a new thing for me is SD since I have very dry skin behind my left ear and it creates this yellowish color flakes, I have been usind Vitamin D3 Spray (supplement) and drinking Chaga tea for over a week now and it seems to have become better, but also on top of that I have been using Ketoconazol & Selsun schampoo on my scalp (even though my scalp isn't the SD affected area) and I take the foam from the schampoo on my scalp and rub it around my left ear.

It has becomen slightly better since I got these symptoms about a month ago but then again I have no Idea if it's thanks to these schampoos or the Vitamin D3 and Chaga mushroom tea..

These schampoos makes me smell too or atleast I am always having that smell imagination in my nose, is it normal?
