i got a rash as well, and i attributed it to the hops extract (i also have a sensitivity to beer, although i still drink it of course). i've been avoiding hops in my products, and i've been rash-free. i also still use the devacare low-poo, but i think the shampoos have less of the hops extract. hth.
