Pureology Thermal Antifade Complex Super Smooth Relaxing Serum Size: 5 oz Pureology Super Smooth Relaxing Serum, creates long lasting smooth hair for all hair types. It is humidity resistant and eliminates frizz. Detangles, moisturizes and protects hair color. Leaves hair feeling soft and shiny. PLEASE READ: I did use this product 1-2 times, but it wasn't for my hair. You will also notice that the pump is not working properly. It is very hard to push down. That is the way it was when I purchased it. The product will come out you just have to give it a good push. The bottle is pretty much full. Purology is a VERY good brand. I use a lot of there products. Great quality products!
