I use Regenepure DR to fight inflammation. It has water and aloe vera gel as its two main base ingredients, along with it containing 1% Ketoconazole. The aloe vera gel and Ketoconazole in Regenepure DR really help to keep inflammation down since those two ingredients have anti-inflammatory properties. I recommend Regenepure DR, it's a gentle shampoo. I have a super sensitive scalp and I haven't had any problems using this product. I use it daily and I'm happy with it.
One of the main reasons why Nizoral can make it worse in some people is because one of the inactive ingredients in that shampoo is sodium laureth sulfate, and that itself is an inflammatory compound. Nizoral also doesn't have anything in it to counteract the drying effects of Ketoconazole.
