Hair stylist question- (prell work like a hair stripper?)?

Question

When I was in cosmetology school years and years ago, lol, they used to tell us that Prell shampoo worked like a color stripper on colored hair. Is this still true today? And if not, is there some other product that works like that? I have covered an ugly red mistake with a dark brown, and now there are patches of red/ rust color and the brown took to some pieces like black. I have two parties to go to tomorrow and need an answer asap. Please help. Thanks!
* PLEASE NO ANSWERS OF GO TO A SALON. I NEED THIS TO BE AN AT HOME PROJECT.

Answer 1

Yes, and baby shampoo works too. It will take mutiple washings and dry out your hair so get a treatment to use afterwards.
