I am a 25 year old female that has been battling with scalp folliculitis for the past 2.5 years. I have been on Bactrim DS for
several years now for
acne, I would say since 2005, but I developed scalp folliculitis in approximately Feb. 2008. I have tried every shampoo imaginable, prescription & non prescription (tar-based, salicylic acid, sulfur, sodium sulfacetamide, zinc, ketoconazole, salicyclic acid AND sulfur combined, hypoallergenic, selenium sulfide).
