Which hair lightener/bleach should i use?
You would have to use peroxide 40 + bleach and then dye it. But once you lighten your hair, and dye it red, if you want to get it back to what it was you will have to do all over again. Take off the red colour and then dye it brown again. I would advise you not to do it. Once i dyed my hair black and now i got tired of it. I am having to do high lights to get it back to normal, cause if i bleach it all, i am afraid my hair will fall too much and it might become dry as well. Think well before you do it. And the best thing to do is to go to a good professional cause sometimes the bleach doesn’t work preoperly and makes your hair orange!! Be careful! Good luck!
