10/3 required

[Nicnicnocnoc75]

Client is base of 7 and would like 10/3 what volume would you use? 30 or 40?!

What brand are you using - Kadus, L’Oréal, Wella, Ikon....?
Assuming you’re fully qualified, this seems an odd question to ask if you’re working with virgin hair, so what are your concerns?

I'm assuming the 3 is gold. There is a lot of informations missing here:
- Is it virgin hair or not?
- What do you mean by 10/3? A lot of brands have differences with their colour
- What is the integrity of the hair?

I agree it seems like an odd question
