I have a client who I’ve been driving an hour to SalonCentric for so that I don’t have to transition her formula. At my previous salon we used L’Oréal and when I moved I switched to Wella since I can get it at Cosmo.

The clients formula is Inoa:
20g 4.62
10g 4n
2g 3n
20 vol

Can someone help me translate this to Wella KP? I’m still learning Wella and this color feeling tricky because the 4.62 reads very purple-y
