2. Big Hair Big hair is sexy, big hair is fun and it’s one of the best hairstyles for long hair ever! So, whenever you wish to give your sleek, straight look a break and try something wilder, scrunch your hair using a maximum hold styling foam and enjoy a head full of sexy waves! Section your hair into a few larger sections then scrunch them individually, securing each one with a rubber band or a hair clip. Blow dry, let your hair cool off and then let your hair down and style as desired.
