Used colour b4 but 4 days later my hair has gone darker again!!

Anyone know why this is? What should I do?

Sounds like it has reoxidised. Did you rinse it long enough. Did you put another colour on it? Found a forum discussing the same issue

I think it's something to do with the colour oxidising again. I had this when I used it previously. Some say it's due to not neutralising sufficiently with the second process but I followed the instructions to the letter and it still happened.

If you google it, there's lots of info. on it. I feel your pain - it's SO disappointing after going through all the hassle of the stripping process.

I use the Jo Baz colour remover and I've never had an issue with it reoxidising. I find it much better at removing the colour uniformly and it's kinder on my hair than the colour b4 one. With the Jo Baz one you can dye it again the same day.
