After suffering through the Cold in the Midwest, my skin and scalp itched from the dry weather. Now, back in the (mostly) warm South, I bought some Suave AD shampoo. My GF thought I had $hit myself in the shower from the STENCH coming from it. I looked at the Suave bottle: Active ingredient SULFUR. The perfumy crap in the shampoo masks the rotten egg smell until you are helpless and naked in the shower, then it hits you full force.
Maybe I should have spent more than $1.50 for AD shampoo. Free is good, hope its a decent size sample.
