I straighten my hair almost everyday, and obviously a heat protector is needed when you are using a flat iron or curling iron.
I have used a few other brands before this one, and I have to say, this one would be in the back of my products shelf.
Most hair protectors are light weight, and only do one thing: Protect your hair. But this product has a bad effect with my hair. It causes some oiliness, and a heaviness to my hair. Using this product is a pain in my rear! I could go without using the flat iron for a few days instead of putting this protector in my hair. And that's saying something.....
