Made with flexing copper plates that shape around your hair, the Dyson CorraleTM Straightener gathers your hair neatly together on each pass. This extra control means you can achieve the same style but with less heat. You'll enjoy shiny, straight results with fewer frizz and flyaways. Intelligent heat control regulates the temperature of the plates ensuring you never exceed your chosen temperature. Plus, the innovative and versatile design can be used corded or cord-free for added convenience! How do I use it: Before styling, ensure hair is detangled and completely dry. For best results, section hair. Begin at medium heat (365F) and adjust up or down depending on your hair type and texture. The flexing plates shape to gather your hair, letting the machine do the work for you. Ensure your hair is in the middle of the plates when styling. The perfect tress size will depend on your hair type. Try a few different section sizes and see what works best for you. From Dyson.
