When styling your hair at home, there's loads of options. The easiest I found is putting the front section of the hair in a victory roll and gripping a hair comb into each side.
Just grab a 3x3 inch square from the middle front section of your hair, backcomb thoroughly from behind, hairspray, curl the end in on itself slightly and pin to the side. Then just grip the combs in and spray again. This takes five minutes and has the perfect balance of vintage glamour and punk that's so signature to Gwen's style.
Another option for the front section is backcoming from the front and rolling the hair in on itself - thus creating a faux smile fringe like 1950s glamour girl Bettie Page. Gwen had one of these in the 90s when she had pink hair and braces. She was so cool.
