So I decided that after many many years of dying my hair with box dye (please dont judge me!) That I need to go back to square one. Lots of research later and I brought this colour remover. Gotta say it smells bad, and has an hour developing time but the amount of lift!! I'm seriously impressed how much of the dye it managed to remove with one application! My hair will be ongoing process and a good cut is happening soon but hopefully this is the start of much healthier hair!
