To create a wavy hairstyle in which it looks like ripples or waves going down the length of the hair, you will need to work with wide sections of hair of approximately 3 inches wide. Once you have combed a section of hair ready to use, spray it with a heat protective spray. Gather the hair together at the root of the hair and wrap it around the barrel. Hold for seven seconds and the slide the hair off the barrel. While the hair is still warm, gently pull on the end of the hair to loosen and elongate the curl. Always start curling hair from the lower sections first and finish with the top layer.
