TheTrendSpotter: Rubber band hairstyles are the perfect choice when you’re looking for a playful and pretty summer hairstyle that’s full of fun. The ‘rubber band’ really refers to small, thin, strong-hold hair elastics – usually colorful – that you can use to create amazing patterns and sections in your hair. They can also be used to elevate and accessorize simple hairstyles like puffs or ponytails.
