The Knot Genie was created to not only to make brushing of even the most unruly hair effortless, but to create peace in households around the world at bath time. It's unique bristles act like little "fingers" gently untangling knots and tangles. The magic trick behind the Knot Genie™ and Teeny Genie™ is one we are happy to reveal. It all has to do with the different lengths of teeth on the brush. When brushing, they bend just right, to gently untangle the hair. And because of this lack of stress, the hair's cuticle stays unharmed… revealing the smoothest, shiniest hair you've ever seen.
