Hi there, I have a client who is currently high lift ash blonde. The hair is a 12 in shade and very ash. She would like to keep this blonde shade but add a very slight pink tinge to the overall colour. Ive been looking at the possibility of a pastel shade but she does still want to look overall blonde. She just wants the hair to shimmer pink in the light. Subtlety is definitely the key in this one. Any ideas on colour ranges and shades to create this?
