State-of-the-art Keratin Infused Tourmaline Ceramic Coating for Nourished Locks: Boasting a keratin-infused ceramic-based layer, this hair straightener brush creates a shielding layer that reduces thermal damage and deeply repairs damaged hair, leaving your tresses smoother and lustrous. Single-stroke Straightening with Patented 3D Teeth: Working with a 0.09-inch denser pitch, the brush straightener widens the touchpoint between the bristles and strands. This design guarantees thorough heating, allowing each piece of hair to attain a super smooth look. Efficient Styling with Broad Surface & Fast Heating: The comb teeth compress locks like many small straighteners, treating more hair for faster straightening than a flat iron. The 20-second heat-up to 350°F greatly reduces your styling time. Safety with Burn Prevention & Auto-Off Features: TYMO’s patented V-shape flame-retardant plastic frame protects you from all sides. The styling brush shuts off automatically after 30 minutes to enhance safety for you and your family.
