Nothing has worked.
I just bought a new supoosedly extra strength shampoo but I'm not sure...
WOuld that be better than home remedies like Listerinne, etc?

It gets expensive buying these shampooss.. but then, the remedies also require money

Regular washing with normal shampoo should be enough, if not, ask your doctor, in one of the 100 other medical illness you have that you see a doctor about.

Listerine?? I've never heard of that as a home remedy for dandruff. I imagine that would dry your skin out and make it worse. Where did you learn that from?

Like chuck said, regular washing should be enough. I use tea tree shampoo and conditioner. If that isn't enough, I'll add a little extra tea tree oil and that does the trick.

Or heck shave your head,

Come on guys.

DHS Zinc is fantastic. Amazon.com: DHS Zinc Shampoo 14 fl oz.: Beauty (http://www.amazon.com/DHS-Zinc-Shampoo-14-oz/dp/B0001EKQRW)

For really stubborn oil, use a mix of 1/3 Cepecol mouthwash, 1/3 witch hazel and 1/3 water.

Actually, premix the Cepecol and With Hazel to a 1:1 ratio. Then add 2/3 of the mix to 1/3 warm water.
