Buy more than you think you'll need!
"I think the instructions say that you just need 2-3 drops to refresh your bottle, but I find that I need to use a lot more. I would definitely say, buy 2-3x more Revive than you think you'll need. I have 20 Dazzle Dry shades and only bought 1 bottle of Revive, I wish I'd bought more!!"
