Review on 🌱 Clairol Root Touch-Up Semi-Permanent Hair Color Blending Gel, Dark Brown (Pack of 2), 1.5 Fl Oz by Tracey Brown

I am 100% satisfied with this product. I have about 1/2 inch of solid greyish white growth at the roots and I used light brown. I left it on for 45 minutes as my roots resist color absorption. It works to mix gray and white but doesn't hide it completely. In my case, the roots look light, not grey. I can't say anything about the duration of the effect because I used it literally 30 minutes ago. It's so easy to use and doesn't make a mess. Highly recommended! I will buy more. The photo was taken in natural light. UPDATE: After the first wash, the color stuck to the roots. Again, it doesn't cover them completely, but they blend with the rest of the color.
