has snyone used this technique? Client base 5 with bleached ends about a level 10-11 quite brassy regrowth about 2-3 inches, I feel it should b full balayage to break the demarcation line or may still look odd? Client doesn't wear her hair up, it's shoulder leghth. I was going to use luo 5,3 and 4 roots rinse&tone ends at basin? I love redken to tone but I've only used the 9p,v,b&t could work on ends? She wants it quite natural a warm stretched root and subtle lighter ends?
