I received this Wella Brilliance Treatment in my April Glossybox and was excited to give it a try. It’s made for color treated fine to normal hair and my hair is both color treated and fine. After shampooing your hair you apply it to went hair and leave it in for five minutes then rinse it out just like you would do with any other deep conditioner. It rinsed out fairly easily and my hair felted very soft while the water was running over it. When I was done I was able to get through my long wet hair about the same as I do when I just use my normal conditioner. How ever once my hair was dry it didn’t feel as if I had even used a normal conditioner on it never mind a deep conditioner. I was very disappointed in this deep conditioner! My hair looked and felted stringy and looked dirty with in a few hours. I wouldn’t recommend you spend the extra money on this Wella Brilliance Treatment at all!
