Jordan, my experience with Clariol root touch up was not good. I have very stubborn grey hairs on temple, hairline. Also, with Clairol you can't wash your hair after appling and letting the dye set for the suggested time. Hate that!!!
I switched to L'Oreal Root Rescue and have had great results. Covers my stubborn greys, and the directions say to wash your hair after set amount of time, 10 minutes. Love! It lasts 2-3 weeks. But it's so much easier than running to the salon, etc. Good product. Try it!
