Techniques for straightening thick, loose curly, medium hair?

What i do is i wash it with shampoo and then i use pantene anti-friz conditioner it's in a little purple bottle then i blow dry my hair but dry it from the top down it makes it less frizzy. after that i section my hair of by layers (top, middle, and bottom.) i pin up the top and middle and i straighten the bottom, then i take the middle down and straighten that, and finally the top. Oh use protectant spray or gel. I don't have any yet, but there is stuff you can put on after straighten your hair that keeps it shiny and everything it's Got2b, but i haven't tried it yet, but someone told me it does good. It's in like a pump type bottle. hope i helped some.
