what kind of trouble with new formula of the color You mean?
i still having probs with vibrant reds and violets. and while using the color as demi permanent to get nice coverage on bleached hair.
Well with the new color I have to use 30VOL to cover grey hair completely ... I also have to add color shots for
warmth. I love to use the PM shines to tone and to seal in reds!
NBs are warm, Ns are a real natural now as they took the yellow out, and NNs are cool.
NNs are designed to give you superior gray coverage and if you can, let them develop for 45min, if not, then 35 like the rest of the color will be fine.
I like to mis mix NBs, Gs, with a bit of A. Nice natural color and covers grey good. ( not a lot of A if somone is 50 % or more)
with the new PM the Color you now have 3 familes of color! ( check the color poster)
1. n,nn,nb with 100% brown
2. na,cb,cm,rb,wm,wb with 50% brown
one of my favorite is 1pt NN + 2pts NB + color shots blue
have a great day
all the rest have NO brown
so you can formulate depending on the grey % using colors from the first two familes as a basic plus a color from the rest for shade
ex: for vidrant red with 50% grey , 1pt n or nn + 2pt r or rr + c sh red
Does anyone remember how much ammonia is actually in the Paul Mitchell color? I always forget the exact number!
