Hi everyone! I'm a newly licenced cosmetologist and have a client who currently has golden blonde hair (her natural is about a 4 or 5 and we used Wella Koleston Perfect 12/81 with 40 vol to achieve her current golden blonde (in picture 1). She wants to go to a light brown (exactly like picture 2) and I was just wondering what the best way to do this would be with Wella? Do you think that I will need to pre pigment? Does the target color appear to be just a neutral color or not? Thank you!
