Best Toning Shampoo
Joico Color Endure Violet is the greatest for toning yellow/brassiness. If you need a MAJOR tone, apply to DRY hair and let sit 10-20 minutes. The ends of your hair may turn silver before the mid-
shaft/root area, so, I tend to apply in sections and let sit, 10 min for the roots, then apply to mid-shaft for another 5-10 min, only leaving it on the ends for 5 min, but then, I have a TON of residual damage to the ends, so, I go silver FAST.
