I have seb derm on my face and scalp along with folliculitis. I get folliculitis on my chest aswell.
Since I dont have a shampoo with zinc in it I have used Dermadoctors born to be mild cleanser which contains 2% pyritione zinc and my face/scalp and chest feels much better after I've used it. It really dries out the skin and helps with the itching pustules.
Been using it for about 1.5 weeks and it has cleared up pretty much of it but I have not gotten rid of it completely.
