What color remover worked best for you, for removing dark colors?
*waves* i used colour b4 which worked well. I think you can use it up to 3 times if I remember right bit I will warn you it stinks so bad so you'll need a well ventilated room ad follow the instructions to a T. I had jet black hair for years and used this. It's turned my hair dark copper to begin with, then light copper to medium brown to light brown. It worked really well and didn't damage my hair either x
It depends on the country you’re in. In the US the best one is color fix and there’s not really many other options that aren’t damaging.
In the UK there’s a lot more choice. I like Decolour Remover best.
I've only used Decolour. It stiiiiiinks but really works.
