I washed my hair, went down to my friend’s house so she could take a picture of the back of my hair. A year ago my hair was totally white. Now this is how much of my natural hair color is showing. I was a brunette with very dark hair. The lighting in her house is different than mine and this was taken on my cell phone. I have no idea how much white or gray hair will disappear but at least it is working and I do it via remote. So it can be done. To what extent I don’t know yet but am satisfied so far. As for how it looks for the color, there is NO blonde at all in the hair. My hair was white. Now it’s mixed. You need to click on each picture to make it bigger and it won’t be so cloudy looking.
