Cimorene

I think everyone's cuticle is different! The only way to tell is to try it. I have gotten a successful semi-take from a second color in the past, but there were like 2 weeks between dyeings that time and the second color did a) show up different (because of mixing with the color underneath) and b) fade much quicker. Same on Wax's hair which has a far different cuticle, except the mixing was much more profound there, and the fading even faster.
