Yes you do. If you just applied orange on top of the existing brown color, you couldn't see the orange, the hair would still look brown.
You can dye it with hair products or you can bleach it
1st use bleach, then the dye
Sure
no you cant would have to be permanent high lift tint or bleach
You can dye your hair any color as long as its darker than the color it is currently dyed. But there is always bleach.. But it's super bad for your hair.
no, you have to bleach your hair for it to show in your hair
I think bleach blond
You most likely have to bleach your hair first to a light blonde, then dye it light blue.
yes but it will turn red
The first thing you need to do is bleach it. Second, dye it the color blonde you want. If you only bleach it you will have more then one color blonde/orange.
yes with a bleach hair dye ------------------------------------- When lightening dark brown hair, it's best to use bleach with 20 or 30 volume developer. Using a high-lift color as described above will result in a brassy, orangy color.
I got highlights once and i have brown hair, i got blonde, and im pretty sure you have to bleach it but i am probably wrong.
