Okay so I ALWAYS use a protective heat spray every time I use heat. It coats the hair, leaves it shiny, helps straighten, an most of all helps Protect from damage. I'm very careful when I pick products to use. I never want to use anything too heavy. I stay away from petroleum based products. I found this product on one of my many visits to Sally's. It's called Ion straightening solutions. It's paraben Free and 100% vegan. I love it because it keeps the hair flowing and definitely helps with the straightening process..It retails for $7.49. If you use heat often it's a must try..you can find it Here!
