How can you straighten your hair fast without a hair straightner and it wont damage your hair?

Well, first you have to wash your hair with straightening shampoo and conditioner.. but not too much. You can mix the shampoo with water, 50%-50%, and use pure conditioner. After, dry your hair with a towel, blow dry it, then straighten it with a hair straightener. Straighten your hair by a group of strands at a time; from under your hair to over, then the bangs. Put serum (not too much) and then hairspray. Also, you can use coconut oil or Arabia serum.. it usually works the best..
