Ok, so for the last year or so I have been dyeing my hair. First with store boxes, then "unnatural" colors. I have bleached it twice in about 7 months and it seems fine. I most recently used Raw deep purple, however, after 2 months it is fading pretty badly, as those colors tend to do. I am naturally light blonde, with very non-porous hair, necessitating the use of bleach. So as I said it is currently a faded purple, much darker in some spots than others. My question is:
Do I need to bleach my hair before dyeing it back to blonde, or should a permanent color just go over the purple?
Thanks

Please do not apply a permanent hair color on your hair. It will make matters worse. If you want to go from purple to light blonde, you will need to strip or bleach your hair to a pale yellow stage and then apply a toner. I would recommend that you let a professional fix your hair.

Im having the same trouble at the moment. Ive been using Schwartzkopf XXL Colour - Cyber Purple. Recently I consulted a salon about the issue at hand and the stylist told me not to bleach it as it kills your hair (which I already know). She insisted that I tried semi-permanent dyes - brown in colour - for a bit to get the health boosted more. Then she suggested I try a permanent brown over which I'd get blonde highlights. It takes time I guess but bleaching is just hair suicide! :( Hope this helps and good luck!

You won't be able to dye your hair back to blonde simply by using a permanent color over the purple. "Color won't lighten color". You may have to bleach it, but before you do that, you should use color remover, ColorFix, Color Oops, Igora Phantom. Those products will dissolve most of the artificial color so that it can be washed out. If you don't get it all out, it will "redevelop" simply by reacting with oxygen in the air, so you may need two applications. There may be traces of residual artificial pigment that will have to be bleached out.

If you attempt to bleach the purple out before using color remover, you will probably fail -- and after doing that, ColorFix and Color Oops will no longer work at all (overoxidized pigment can't be dissolved).

PrettyLady is correct that you will most likely have to lighten to pale yellow and then tone it.

I have a problem too. I had purple in my hair a while ago and it also kept fading to a sort of red. I have for the past year had brown over the top and also a golden brown on parts but have been growing it out. My natural hair colour which is mousy brown has grown about 7 inches. A couple weeks ago I decided to go blonde only on my underneath layer. Of course, the blonde came out great on my natural light mousy brown hair but on the died hair that's still growing out which previous has has purple in came out a peachy colour. I have used 3 belle blonde prelighters which lighten natural dark or dark died hair, and 4 Schwartzkopf blondes on the peachy parts of my hair. It is still not blonde enough. Will it ever go blonde?? I reckon it could just go white as I don't like pink can go yellow blonde.

[I mean don't think pink can go blonde

I have the same problem to I just recently died my hair half purple and it was blond and it is already fading. And it has only been in for about 2 weeks. I didn't get mine done professionally I bought the store brand from Walgreen so I don't know if you can or not I am wanting mine back to all blond and it took me a long time to get it blond... I don't want to strip it cause it will take a long time to get it back to the blond I want so what everyone else says might be good!!

Hope this helps haha I am in the same situation but mine is only half purple and its not a dark purple!
