Ok so i am dying my hair again to the same green. Last time it left it in for 30 min and it faded in like a week. Is there a way...like not shampooing and conditioning for a couple days or something to get it to last longer?
hmm try the conditioner and stuff that's made for colored hair or maybe its the brand of dye you are using. I'm not really sure of any tips or tricks...i usually dye my hair and let it fade and find a new color or just let it go back to normal.
It depends on what dye you use. I personally prefer special effects. Also wash your hair with cold water not hot. The cold water will help the dye settle in while the hot just strips it away.
I would drench my hair is the dye, then leave it in as long as possible (2-6 hours or so), some people sleep with it in. Good dye and blow drying(heat to soak it in) occasionally helps too. And colored treated shampoo.
