I have been really mean to my hair. I have used Henna in it for quite some time which I have loved. I thought I would try something different, so I put a "wash out in 24 washes" color over it. I used a dark brown and needless to say, it was not washing out; and I didn't really like the color on me. Well, rather than waiting it out, I went out an bought Loreal Color Zap to get most of the dark color out. Well it worked, but the roots of my hair (new growth) turned a lot lighter than the rest of my hair. I used a medium golden brown "wash out in 24 washes" color after I used the Color Zap and it worked nicely except for the lighter roots. I guess my question is, what can I do about the roots? and when do you think I can use Henna again? I would really appreciate any help I can get on this! Thank you!
