*Update*- Okay, so I dyed my hair Blue Black using the Revlon Colorsilk. Because my henna'd hair was bright with very orangey tones I used the black dye with a blue base to neutralize the orange. First, I used the Colorful Neutral Protein filler. I used this because I lifted my natural hair color before I used the henna. I wasn't really sure if I needed this because I know henna acts like a protein on your hair. But because I haven't henna'd in about 4 months, I figured it would be ok. It worked wonderfully!!! I had been complaining about the henna removing alot of my curl. I used Joico K-Pak reconstruct conditioner a few weeks ago and it helped some. But this Colorful filler done magic! My curls are back!!! Of course it also helped with making sure my color came out even and the dye took well. I expected to see some red still coming thru but as far as I can tell it is very, very black. I really love it!! I also like this Revlon Colorsilk brand, it was very gentle. It also came with a nice conditioner. So in all, I'm happy I decided to cover up the henna red. I have said about 5 times that I will no longer henna and this time I REALLY mean it LOL!! If anyone wants my henna, please check the swap forum. I have some for sale, but I am willing to do a swap. I really would like to get rid of it.
