We have all been there!! One day your hair colour is fine and the next day, you have a big night planned and you're looking in the mirror under a bright light and realize you should have booked in for a root touchup. Color Wow Root Cover Up is a major game-changer in the beauty industry, I personally love it. We have had it in the salon for 6 months and the client feedb ack is great, everyone loves the results. What is it? Color Wow's Root Cover Up helps to cover grey roots.
