Our patented new BIO-FLEX Shine is an incredible break-through with a handle made with cornstarch! With a unique fluid design and premium natural bristles, the BIO-FLEX Shine distributes natural oils to shine the hair. 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.
