White Roots & Natural Hair Color
Q: I have darker blonde hair, and I tried to put bleach blonde highlights in my hair and I did too much and now all of my roots especially on the top of my head are almost white.What color should I do to get rid of these highlights because I hate my hair and want my natural hair color or close to it back?
A: Okay, in your case, I recommend that you get a hair color that is approximately your natural color, and purchase a 10-volume peroxide developer.
The reason for the non-standard mixture is to make the processing a gentle as possible. Given the level of lightening, you should get adequate penetration of the color. If the results aren't as dark as you want afterward, you can repeat the process after giving the hair a few days to "rest" in between.
