I used The Color eraser from affinage and washed my hair about 10 times to get it out then used the post eraser and it came out a browny redy color (i had red on before the black) i know now that i needed to use the color eraser a second time to try and get the red out but because my hairs long i'd used it all so after i used my color equalise treatment to help the porosity of my hair i put a brown dye over it and it turned out BLACK..but my roots are ginger :S i know people say you should use a shade 1 or 2 lighter than you want but i did and it still turned out black..its my birthday monday and i desperatly need to sort my hair out..i need to get it all brown and get rid of my ginger roots. I think Im going to buy 2 lots of the color eraser and try again im soo upset ive spent all day on it and wasted about £25. I know so many people are going to say go to the salon and have it done and i wish i did now but its too late and i havent got the money now so im going to try and use the eraser again..i'm pretty sure it'll work :S any1 got any advice?
