Review of Overtone’s Blue for brown hair - oVertone Haircare by thetasmom13

I am over half natural grey. Overtone themselves said the colors would NOT stick to my greys. I tried it anyway. They were thankfully wrong. I dyed my hair black for years because I wasn’t a fan of my natural dark hairs reddish undertones. When I allowed my hair to be completely natural, I had to swallow the reddish tones I hated. I was bored. This darkens the darker hair I have to a dark blue. I love that. And the brightness of the blue that sticks to the greys is intense and awesome. I wash my hair once or twice a week, so it lasts a long time on me. I’m obsessed. I keep them on hand in case I get bored. Be careful though! It’ll dye EVERYTHING if you aren’t careful. Gloves and gentle application and rinsing in stainless steel sinks are recommended. Then I scrub the sink!
