I have very old foils on my hair now, want to color my hair all in one color medium brown, but I don't want the color to fade within weeks where it was bleach.. I HEARD USING A FILLER WILL HELP..
How do I use it..
:confused:

Yea a filler is a great aid to avoid fading!however in my 7years of doing color in salon I have only used a filler if blonde highlights were extremely light and lacked all pigment! If your blonde appears to be goldish or fairly warm? You can simply avoid the filling process and just use a straight color! If it is platinum blonde and extremely light? Yea filler is needed4sure! If its somewhat in between? Or you have some platinum and some goldish blonde just make sure your color you apply contians some gold pigment! I know this prob sounds confusing and I'm sorry!
