Catwalk Camera Ready Shiner and Defrizzer by Tigi is a great addition to my hair products. So far, I have only used this product when straightening my hair. My hair stylist first introduced me to it when she used it on my hair while styling it after a cut and color. I love it. The only things is, make sure you do not use too much! A little really does go a long way. If you spray too much on your hair, it will become really greasy. So as long as you use it correctly, it is wonderful. When styling my hair straight, I first blowdry it after washing, (or sometimes I let it airdry if I have the time) then flat iron it. The key to flat ironing is taking very small pieces of hair at a time. I start by leaving only the very underneath section of my hair down and clipping the rest up on top of my head. I then spritz a very small amount of Catwalk Camera Ready Shiner and Defrizzer on that section. After that I take the flat iron and iron it piece by piece. After that section I let down a little bit more from the clipped hair and so on and so on. This can take quite a while with my hair because it's so long and very thick. Overall, this product is great and I'm really glad I purchased it. It makes my hair so silky and smooth with no frizzies. It's lasted for so long since you don't need to use much at a time. I'm recommending this product!
