What the community is saying

Real hair. Real results.

"I've been natural for 6 years and never understood why products would work for a few weeks and then stop. Qoyl told me it was the glycerin in my leave-in — I live in Chicago and it was pulling moisture out during winter. Game changer."

"As a 2c wavy, most natural hair content isn't for me. Qoyl actually evaluated products for MY hair type and told me which silicones were fine vs which ones would weigh my waves down. Finally."

2c wavy, low porosity · Seattle

"I searched my holy grail conditioner and got a 91/100. Then I searched the one that's been making my hair feel like straw — 34/100. I literally screamed. This is exactly what we needed."

4a, medium porosity · Atlanta

"My daughter has 3c curls and I've been guessing at products for years. Qoyl built her a profile and now I know exactly what to look for on ingredient labels. Worth every second."
