Just bought some really cheap sponge mix from my local shop, the main ingredient of which is Wheat Flour.
Is this going to be OK for getting out of hair? I've been warned against using flour and water for this reason, but told that sponge/cake mix was no problem. I have quite long hair and live with folks so....y'know

It is "Green's Classic Sponge Mix" if you want to look up the ingredients.
