#1: Coloring products
I have been coloring my hair for 10 years or more..not because I want to but because its premature gray!! I have an awful time getting it to color the gray unless I go very dark on top (that makes the bottom way darker)..Then I decided to just do my roots, but I have a problem with my hair holding the color for more than a few weeks..Someone mentioned to use a pre treatment (that opens the hair shaft or something like that?) then the color would take better...Has anyone heard of doing that? I use light ash brown on the bottom and medium ash on the top..
