My husband has had terrible seborrheic dermatitis for over 20 years This is what cleared it up, equal parts of flowers of sulphur and cream of tartar bound together with honey until it forms a smooth paste, depending on honey used the paste may solidify after a few days this does not matter. Take one teaspoon per day it tastes lemony.For the first few days you pass very smelly wind but this wears of, my husband said he could feel it working after just 24hrs. I hope this helps. By the way you get cream of tartar in the baking isle, flowers of sulphur I get online not expensive.
