I asked the salon person [who I was dealing with at the time] what I should do if I went too deep with the colour and she said to just apply the peroxide to the hair to lighten the colour again.... I`m unable to give you a `time`on it...just try it for 3 minutes first and see how it goes [ try a very small/unnoticeable section of hair first until you see how it looks] Creme peroxide is a white, slightly ` gooey` liquid/substance. Here`s one example of what I`m referring-to: http://www.ebay.ie/itm/WELLA-WELLOXON-PE...0615751025
and here is an item I found too --I`d advise AGAINST mixing bleach with the creme peroxide.... just try the peroxide on it`s own and keep a close eye on it... I cannot give you any definite timings.....just proceed cautiously! http://www.ehow.com/how_5061121_remove-h...loper.html

Thanks Paul! The dye I used was Just for Men. The dye remover is called Color Oops. It does NOT contain peroxide, and is therefore considered to be less damaging to hair. But this could be the missing ingredient. This product does have amazing reviews, but those are from women using it on real hair. Do you feel peroxide is in fact safe for hair pieces? I wonder if I'm getting a bit too far in over my head here... is it time to take it to a salon? I'm reading now if you dye hair or bleach it, subsequent dyes can turn out quite different than expected. Half the piece is blonde now, the other half brown. How the hell am I going to get it all to be an even shade of brown?
