Unfortunately, I'm not sure if they made it to cover *just* grays, because it does almost nothing to my roots. My hair is naturally black, with some gray here and there and coloured light brown. I chose Light to Medium Brown, and my hair matches the colour on the can. When sprayed on, the product just makes my hair feel gummy. It does not conceal my black roots at all. It only seems to coat it in a slightly lighter colour, nothing like the colour on the can.
I really, really wanted to like to Root Cover Up, as it would definitely make my hair look better in between colouring. Sad to say, it did not work for me.
