Curls are structurally unique—more bonds, more bends, more prone to breakage. The Olaplex Nº4 shampoo for coily, curly, and wavy hair delivers multi-action care to instantly strengthen, define, hydrate and target your hair's unique combination of needs, no matter your pattern.

For all coils, curls, and waves, and all porosity levels. Trichologist Approved. Stylist & Dermatologist Tested. Vegan. Color-safe and suitable for chemically treated hair. Tested on coils and curls.
