Hair dye not sticking?

you shouldn't try to re-dye your hair too soon because the harsh chemicals can peel away the protective layering your hair naturally has. try the Nice N' Easy� color boosting glaze. i also know you can to hair masks made from tea to darken your hair. and if you are going to dye your hair, definitely use shampoo that is specialized in colored hair. it makes the color last longer, gives a healthier shine and works in favor of the dye. good luck!
