I have dyed my hair about 4 times I believe maybe three in the past year or so different shades of brown. I want to go back to natural because it's so many different shades all over my head. It's a dark almost black in the front and lighter brown in the back. In different spots all over have faded to a redish tint of brown and lighter brown. My natural color is more an ash brown light brown with some different natural highlights. I do not what to strip the color and damage my hair. I also want to grow it out, but just need some ideas to help it fade more so it blends better and you can't see my natural roots as well. Help?
