Sienna Guillory’s curly hairstyle gives her a great look and it can look best on the hair which is medium length. To get her style first you must part the hair from center immediately after stepping out of the shower. Then spread a smoothing cream over the damp hair and use a diffuser to blow dry the hair which will add more natural waves. Once the hair becomes fully dry, curl the hair by wrapping the hair around a one inch curling iron. At last finger comb the hair and spray an anti-frizz hairspray all over the hair to end the styling.
