For a gray color or sliver your hair must be a white or pale blonde, then just get a black dye (manic panic black is great for a first time dye ) and add conditioner, (white in color silicone free white rain at dollar tree is what I use) use half a spoonful of dye and add conditioner into the bowl with the dye , add more dye if you want a darker shade, add ply leave on for a hour or two, then wash with cold water, then BAM beautiful gray or sliver hair :) already made sliver or gray dye you can get is pravanas sliver and color brilliance titanium. I haven’t used either of the color but those brands I have used in other colors for color brilliance you will have to use a bit of water or developer 10 to make it spread able cause it’s thick . Hope this helps! Thank you so much ^.^
So by April my hair will be a new color (pastel of course ^.^ ) along with a new hairstyle/cut which I feel is just perfect and exactly what I have been looking for<x3 so excited!
