This is another product to removed brassiness from blonde or grey hair. While the product worked wonders in giving back cool tone to the hair, I just hated the process of using it. The instructions tell you to apply it to dry hair, wait for some time, and rinse it out. The whole application was quite easy, but it took at least 15-20 minutes for me to rinse it out of my hair. Just like with Madison Reed hair dye, this gloss seemed to dry out my hair badly and they seemed to be glued into one big mess. I couldn't even put my fingers through the hair to properly wash it out, and had to use conditioner for a few times just to be able to reach all over my hair to rinse the gloss out. No matter how I loved the hair dye and the gloss, the effect is just not worth the pain I went through in the process of using them both.
