Here is a color I did in early May. This is my friend Nita and she had an ombre done about six months ago and her hair has been growing out. She has had several variations on red/brown since then and the ombre has been covered at times but always comes back. She has a lot of color build up on the midshaft so I mixed some deeper brown into her regrowth formula then diluted and added more red to the formula (and waited fifteen or so minutes) before applying to the midshaft, then emulsified at the sink for a few minutes. I used the ColorTouch line from Wella with Emulsion.
Formula: Wella ColorTouch: .2 6/75, .2 6/35, .1 8/81, .3 6/7, .2 4/6, .2 44/65, .2 6/4 with double Emulsion
