In this case you're probably going to need to use hot rollers.



After applying the hot rollers to your entire head and allowing them to set, lightly brush the resulting curls and spray with hair spray to hold. You can also use standard hair rollers on damp hair or fashion your hair into pin curls using bobby pins and sit under a hair dryer until the hair is dry. Use hair spray to hold your new curls.How do I get big curls without a curling iron?
