I have been coloring my hair using different products for awhile now. Most recently, Fat Foam in light brown. I just used Loreal Sublime Mousse in Medium Golden Brown and my roots didn't take the color. I have more than 50% gray. If I use Color Oops, will it take out more than just the most recent color?

Hi I'm Justine no I'm afraid not at best the product may take out your last colour or may lighten your hair and at worse do nothing at all . You say your 50% grey, removing colour from hair is hard and when you have grey in your hair you should go to a salon to get it fixed .I f you let me know what colour it is right now and your desired end colour I will help you as best I can
