Our patented new BIO-FLEX is an incredible break-through with a handle made from 100% cornstarch! With a unique fluid design and flexible pins, the BIO-FLEX is perfect for wet or dry detangling, to prepare the hair for styling, or just a quick tune-up. It pairs beautifully with other Bass Brushes. It’s durable and will function optimally for years, but when it’s finally discarded, the handle organically breaks down to create a natural fertilizer.
