All NuWay 4Hair product claims are crtified by Certified By Internationally Recognized Independent Testing Firm, SGS Testing Labs. The BrainyBristles have BUILT-IN material properties (NOT JUST SPRAYED ON) providing built-in material properties that reduces static electricity in the hair when brushing. The BrainyBristles will not melt at temperatures of 180C/356F degrees (Certified by SGS)! The BrainyBristles intelligently brush through the most troubled Hair, but because the nylon BrainyBristles are unique compared to the industry leading product, they reach through the hair to penetrate and touch the scalp. This allows their Argan Oil infused Double-Dipped BrainyBristle tips (CERTIFIED BY SGS), to gently massage the scalp and then brush along the entire length of the hair shaft. This makes the Junior C brush unique in its performance with thick, very curly, or ethnic hair types. And with the Argon Oil Infused Bristle Tips, Everyone Is Genuinely Amazed At How Soft And Shiny Their Hair Becomes When They Use This NuWay 4Hair BRUSH!!! The special shape makes each stroke highly efficient and uniquely different than any other brush
