The deep wave hair offers beautiful thickness and lots of versatility. The natural curls bounce back easily when wet. These defined waves allow you to create a fabulous deep wavy hair style or brush through for a natural afro - inspired style. Hair has lots of volume and body with a look that feels extremely natural. Straightening or iron curling the hair is not recommended as it ruins the natural curl this hair comes with. With time the curl will become looser. Regular washing and detangling of the unit is necessary for the good maintenance of this curly unit.
