Review (5/5): if used correctly lasts 3-6 months
I love this teal it lasts for several months. My secret to perfect teal color, bleach blonde until white, remove brassy colors or that area will turn more green. I like lighter teal also, if used straight out of bottle its way too dark blue for me its a dark lake blue. Add onto dry hair, mix color in a bowl, add conditioner until desired color appears. then apply on all bleached areas. Any bright punk colors will not show unless you bleach, sorry unless you have natural white hair. Leave on for at least an hour or cover and leave over night. Care, to keep you color, do not use shampoo, any type WILL strip it. Use conditioner only. Rinse with cold water, heat will wash it out. This is the only brand of punk colors I have ever used that has this lasting color tone. Of course it will fade eventually. If you want a more permanent color always look for demi-permanent. Semi means not very long. A couple washes at best. Good luck, and have fun with your wild colors!
