Hey there, I'm sorry to here that you are going through that condition. I've never had p. foliculitis but I do have seb derm and rosacea that causes redness, itching, and flakiness all over my cheeks, sides if face and chin. I have heard that Nizoral is good at killing the yeast that plays a role in many conditions including the one you have mentioned. I've tried ketocanozole cream 2% and although it did remove flakes it made my skin oily and breakout. Unfortunately yeast may adapt to products that can keep it under control like Nizoral. Many suggest switching up your routine, such as rotating between two antifungals that work well for you. If the Nizoral is working that's great. You can slowly start using it less once the condition is clear such as using it from twice a day to once a day for a bit and then every other day. These things are tricky so I feel your pain. I'm currently going to try promiseb which is a prescription non steroidal cream used for itching, flaking, redness, and pain associated with dermatitis. I also recommend trying to stay away from topical steroids if the Nizoral happens to not work as affectively. Rebounds from those are not fun and you can become addicted very quickly. I think the Nizoral that is commonly feared and looked down upon is the oral antifungal because it takes a great toll on your liver. These are reserved for extreme cases when all other resources have failed.
