The unique twists and turns force the cuticle layer of your hair to open, making it difficult for natural oils to travel down the hair to moisturize and protect the entire strand. Curly hair can often seem “dull” as light gets trapped in the curl pattern and refuses to reflect. Layering products in the right order (Leave-In, Oil or Shine Mist, then your Styler) will help seal in moisture and prevent frizz.
