Hi guys, I use Schwarzkopf in my salon and a client wants the 'grey'. I'll post a pic of her hair for you to see but I was thinking of doing a mix of 9,5-22 with some 8.29 in it. Question is, can I do this with 3% on wet hair and will it achieve the violet/grey she wants? Any help would be appreciated ![:)]( "Smile :)")
