Bad reaction to zinc pyrithione

[akai]

Ran out of Nizoral so I used a head and shoulders knockoff for a couple days until I get more. Holy Shit, scalp is on fire and I have crazy dandruff. Anyone ever have a bad reaction zinc pyrithione shampoo? The first and last time I'll ever use it.

Btw, can anyone recommend a decent non-sls shampoo for daily use??
