I have just had a client asking me to do her hair. She has bleached hair all over with the remaind of pink crazy colour which has almost washed out. About 1inch of root growth with is a base 7 with around 30% grey. She wants to go back to her natural colour, maybe a shade lighter with some blonde foils throughout as she doesn't wnt the same colour all over, she has warm skin tone and wan't to keep the colour warm with golden tones.... I'm gonna be using wella colours... advice please! Thanks very much!!
