I thought long and hard about this one. This may sound crazy, but seriously i think this is a manic panic color. I also think its a full head of weave, because to get this color you will most deff have to bleach. (sorry) Not alot i dont think, maybe just as light or a little darker than your highlights would get the job done.
This color/ colors ( i see variations) look like that of joss stone and Charlie Baltimore (remeber her
), and its known for a fact they both used manic panic to achieve their colors.

That really is the way to get the color closest to the one she had. I recommend colors Rock and roll red, vampire red and wildfire.
there are pix on the website and manic panic ( because its vegan and actually doesn't harm the hair, you hear ppl leave it in overnight ) it fades VERY quickly and Satins like a mo fo (trust me) The fading isnt really a problem because you can add the color to your conditioner.
I really don't know of another color that provides such a rich color. If anyone else does, please do tell.
