Hi geeks
I've recently trialled nouvatan and have been converted! I'm in the process of choosing what colours to go for and I'm thinking 8 and 12%
However I understand that I can mix these two to make a 10% providing I mix the same amount so my question is if I mix 25ml of each do I have to ensure I use it all on that person or does it not matter as long as its had the same amount in xx
