Best shampoo poll

[admin]

All the available shampoos for eczema boil down to more or less only 4 active ingredients.  The Denorex brand offers three out of the four: http://www.denorex.com/
The question remaining: Which ingredient helps best?

SELENIUM SULFIDE
H&S etc.

SALICYLIC ACID shampoo
Denorex, Dermarest etc.

PYRITHIONE ZINC shampoo
Denorex and Head & Shoulders  etc.

COAL TAR SHAMPOO - TOPICAL
Denorex, Tegrin, Zetar,Neutrogena T/Gel, Pentrax, etc.

I use sometimes the Selenium sulfide shampoo from H&S but the smell of you hair afterwards is terrible...
