Chopstick Styler conducted extensive, scientific research with a determination to overcome 2 perennial hair styling issues - curl longevity and curl suitability for all hair types. Their research uniquely revealed that rectangular-shaped barrels hold the hydrogen bonds in hair more effectively than traditional round-shaped barrels, creating an edgier kink and significantly reducing curl drop rates. Removing the need for hairspray, Chopstick's signature stylers guarantee your style will last for up to 3 to 5 days, whatever your hair type.
