The simple cure that worked for me.
I found this cure on a similar support forum several years ago.
I had treated my moderate to high level Seb Dermatitis for about 12 or more years using prescription steroid creams, applied once a day. They'd work for a couple years and then they'd loose their effectiveness -- I'd then get a new prescription for a different formula.
One day I found a forum were I learned about apple cider vinegar. I know it sounds hokey - but the forum members felt quite strong about it. They preached applying to your face or wherever, and combining it with some diets or avoiding various foods and alcohol, and also drinking it.
I don't really have the fortitude for a lot of strict diets, and I like to drink alcohol. But it's not very difficult to simply apply it to your face...just use a regular cotton ball and wipe it on.
So, I bought a bottle (any health food store). IT WORKED!! In two days, my skin was clearer that it had ever been. Just amazing... YOU MUST TRY THIS!!! I apply it every morning..very easy. I very occasionally have to apply a steroid cream still, but less than once a month.
Sometimes it burns a little at first. Some people's skin might be too sensitive to it - I hope you aren't. Make sure you buy the natural one with the "mother" in it. It's a little cloudy. Good luck.
