People were telling me that it was time to cover all my gray hair. So I covered it in purple :)
The pastel is perfect; it leaves my brown hair brown, and all the gray is a lovely purple.
I use the deep conditioner on dry clean hair and leave it on for an hour with a shower cap on, and the daily conditioner I use every three days *applying to dry hair, then showering and rinsing it out (so leaving it on about 5 minutes)- no shampoo!* I do 1 deep and then 2 daily, then shampoo/condition with sulfate-free shampoo/conditioner, let dry and then apply the deep that evening.
When I had had my hair professionally colored, it started breaking off after a year. With Overtone, it's never felt better- silky soft and smooth and amazeballs!
I LOVE THIS STUFF.
