Hi guys, I mainly work with Asian hair (going blonde) but was wondering which purple shampoos are best for pre toning? I use fudge but I find it drys out hair a lot and really doesnt make that much of a difference. I've seen a lot of videos on Instagram about fanola shampoos but it just seems too good to be true haha. Are fanola shampoos used for pre toning really what they claim to be? Thanks x
