I'm a HairDResser but I need To know About FILLING!
I am going to color my future sis-in-laws hair. But she does her own Color usually! I know a big No No! But anyway... her hair is very curly thick, and dark. So has about 5 inches of regrowth and her ends are all highlighted blond that she did her self. I 'm going to dye her hair dark red so I know I need to fill her ends or they'll turn pink. So I apply the Filler to just her ends wash it out then apply the allover color? Any suggestions. I just want a few ideas. THANKS~~
