This worked perfectly for me! I've been using evil products from Proctor & Gamble that perform animal testing and use toxic chemicals to lighten my hair. I wasn't sure if Ecocolors could lighten my hair to the color I desired but it did! And it looks even better than any Clairol product I've ever used. My natural hair color is light mouse brown/dark mouse blonde and now it is a warmer yet neutral lighter blonde. It also took the brassiness out of my already color treated hair and blended it with my grow out. I highly recommend this product and will now use it every time I color my roots.
