      • Crown covered perfectly.

        I usually wear a hat because of that bald spot on my crown. Honestly didn't think this would work, but look at the difference. This was just a quick sprinkle after drying my hair. Can't even see the scalp anymore.

        James D., Chicago, USA 🇺🇸

      • Easy to use solo

        My bald spot has been getting worse lately. I was worried it would be hard to apply on the back of my head by myself, but I just use a hand mirror and it takes 20 seconds. Matches my natural hair color perfectly.

        Mike R., Austin, USA 🇺🇸

      • Passes the daylight test

        I was most worried about how this looks outside in the sun. Took this on my patio—no green tint, no shiny scalp. It really is undetectable even in natural light. Big relief.

        Omar K., San Diego, USA 🇺🇸
