L'oreal color rays is made specifically to show up vividly, even on dark hair. It says so on the package as well, so don't worry about it being dull. I've dyed my entire head pink, from black, and it worked very well. Good luck! :]How long does L'oreal colour ray last and would it show up that well for dark brown hair?
ok if your hair is really dark you will need to lighten it to make it work really bright





The best way to do this is to bleach your hair with a blonde containing 40 peroxide in it, make sure you do a strand test first.





Then, once it has been lightened it will come out a bright colour, remember if you are dyeing your hair after it has been lightened you dont need a blonde, a light ginger or reddish blonde will be fine.





I suggest Loreal prelightener, or B Jonsons ';Be Blonde'; to lighten your hair, and special fx colours as they last longer...






it works in dark hair if its the natural color. it doesn't work so great on already died hair.
