I am going to be coloring my hair with Ion Color Brilliance permanent color and a Neutral protein filler from Sally Beauty. Instructions for filler read to use on damp hair before coloring. I have been reading up on coloring hair most say not to color hair when damp/ wet. But product directions for Filler are to be used on damp hair. Ion color says to be used on dry clean hair. What is the best method to use so my color will come out right? Thanks
