What is the best hair dye to use to get hair as brightly colored as yours?
I’m no professional, (obviously) but I use either Special Effects (a great brand that comes in a wide variety of bright wild colors) and I also use a professional color called Goldwell (specifically the 8RO color). I know a few people that swear by Manic Panic but it’s been known to wash out quickly, though it looks great the first day you’ve done it.
If you want the color to be brightest I’d recommend bleaching your hair first, unless you’re doing it red. If you’re going to dye your hair red, I’d say start with an orange or redish base color, the color red is the largest color molecule and there for washes out very easily but it will last longer if your hair has some pigment in it.
Also, do your best to wash your hair with cold water only, that way it wont open up the hair follicles and release the color. And unless your hair is really dirty only wash your scalp gently wish shampoo and let the water rinse it through the rest of your hair. When conditioning, try to get as much water out of your hair as possible, ring that shit out, and then put the conditioner in it. (The hair wont absorb the conditioner as well if already is holding water) try to leave the conditioner in your hair for a few mins, shave your legs or something, then rinse. And if you have the option, let your hair air dry because some of the dye will rub off in the towel.
