When performing a permanent wave on hair, proper care must be taken during the wrapping process in order to produce a professional-looking, finished curl. The ends of the hair are protected by end papers; the wraps are required in order to eliminate split-ends and "fish-hook" ends, notes Hairfinder.
A professional stylist sections the hair into widths that are equal to the width of the perm rods. Wrapping too much hair onto one perm rod produces an uneven curl. A hairstylists starts by sliding an end paper up to the ends of the sectioned hair and folding the paper over the ends of the hair. She begins wrapping slowly, keeping tension on the hair at all times. Then she secures the perm rod with its elastic band, and repeats the process over the entire head of hair.
