Ouidad Advanced Climate Control Defrizzing Shampoo (8.5 oz) is a sulfate-free cleanser designed to gently remove dirt and excess oil without stripping curls of their natural oils. Infused with sericin (a silk-derived protein), shea butter, murumuru butter, and ceramides, it locks in moisture, smooths the cuticle, and creates an invisible barrier against humidity

It provides excellent moisture and frizz control for tight curls and coarse hair,
