This question doesn't exactly make much sense, but I'll attempt to answer it. I'm guessing that you're asking if you can cover bleached hair with another colour?
If I am correct than, no. I had a friend who had done that and her hair turned a weird brown-ish/gray. If you want to change your hair colour, go to a professional. It will be 100x better.
no, you've chemically altered it...not covered it or infused it with something that can be rinsed away.
ALL U NEED IS HAIR BLEACH YOU CAN FIND IT AT A HAIR STORE AND THE HAIR BLEACH WILL LIGHTEN YOUR NATURAL HAIR COLOR 2 A BLONDE AND IF YOU WANT ANY OTHER COLOR THAN BLONDE YOU CAN BUY A RINSE OF THE COLOR YOU WANT AND PUT THE RINSE IN YOUR HAIR .. AND BAM YOU'LL HAVE YOU A NICE NEW HAIR COLOR ..
You should bleach it first. Well, it really depends on what color you want it, but usually you bleach it. I don't recommend bleaching black hair though, because bleach damages black hair more than any other color. You may never get it back to your natural color.
No, it cannot. Depending on what type of box color you have on your hair depends on how easy for it to come out. Usually people do bleach to help it come out. But sometimes even bleach won't work. I recommend a color remover or a bleach bath professionally.
You must bleach your hair to get caramel hair color appear like Lauren Conrad's.
Generally speaking, you do need to bleach your hair for blonde hair if you have a darker color.
No if you have a light color you do not thing to bleach it
No, highlights are bleach which is different than color. Color coats the hair, while bleach removes pigmentation from the hair, to take out highlights you have to either color over them, or wait for them to grow out.
bleach
If you bleach your hair before the color will show up better. Especially if you have darker hair to begin with.
its basically bleach with some chemicals in it.
It should turn pink if you bleach where you want the pink to be in your brown hair, if it doesn't turn pink after you bleach and dye your hair then I would keep putting pink over it. If you don't like your hair pink just dye over the color with your hair color.
