I read the reviews & gave this a try, I'm glad I did ! This product stays on till next shampoo without a problem. The other reviewer said it was glop when it comes out but I found if I screwed the cap & it comes out, I brush it on clean surface to even out the fluid on brush. Then hold hair straight to apply near roots. On hair next to face I blend a bit with finger & works great ! I was told that if I used a blond tube it would look like highlights on my brown hair but I don't think it looks like highlights. I do recommend this product.
