Just after a bit of advice for a client I have in when back to work..
my client loves flat dark hair, but doesn’t want to be too dark that it looks black!
I use 5.1 igora on her and it goes flat dark when done,
Then she says it goes warm on the roots after a couple of washes,
I told her...
Natural Level 7 in front/6 rest
minimal grey in front only
Every color combo ALWAYS comes out too warm and then turns warmer as time passes
hair is balayaged with ends being at about a level 8 into 9 neutral blonde-but quite often ashy becasue of purple shampoo to tone out the brass...
