I have used this color glaze in the past with other sheer blonde products. I have dark dirty blonde hair and was expecting this glaze to give me a warmer blonde color. However, I did not see any results when it came to coloring my hair, I even left it on for over the recommended amount of time, but still did not get results. It did not even brighten my highlights like other John Frieda products do for my hair. Aside from the fact that it was not effective, it made my hair really shiny to the point that it looked greasy. The only thing I liked about it was it smelt really good and it made my hair smell awesome. But overall, I was really disappointed by this product and I feel like this glaze was a waste of my money. I would not recommend it. Effectiveness Does not change the color of your hair. Makes hair too shiny and oily. You are better off using styling oil. Ease of Application Easy to use just apply to wet hair and rinse out.
