I have colored my hair at home for the last year. It has gotten almost black and I want a more medium brown. My 3 inch roots are the way I want my color but I'm getting anxious about the rest of it. I have read about all kinds of home remedies... prell, dawn dish det. etc. they just don't seem to work, maybe since the color has been in my hair to long.
I was considering Color Zap or Color Fix... Can anyone with experience give me advice as to what I might do? Should I attempt these? If so, what are the risks of it totally screwing up my hair color?
PLEASE HELP IF YOU CAN.
Maybe I'm not doing the prell thing right. Does anyone have detailed instructions... do you put it on dry, how long, etc.

Thank you all so much!!
