With straight hair it is harder to get waves but it is not impossible. You need to brush a lot,..brush like a mad man. Make sure your hair stays moisturized, Use any product that has the word "curl" in it. Wash your hair once a week. Do the Plastic Bag Method everyday so your hair won't get frizzy. Once you start seeing waves you can use any wave product(Natural Wavebuilder Products).
