Hair strength starts deep beneath its surface with a series of bonds. Disulfide bonds provide important, molecular-level structure to all hair types and textures. Strong bonds are vital to hair strength, elasticity and flexibility. Increased breakage and fragility is a sign that disulfide bonds have been broken. Our unique OLAPLEX Complete Bond Technology™ works on a molecular level to repair these bonds and restore hair’s strength.

The ability for hair to reflect light depends on intact bonds in the cuticle and the balance of lipids and amino acids. Healthy hair—whether straight, wavy, curly, or coily—can have shine or sheen depending on moisture levels and light reflection. Damaged cuticle, moisture imbalance, and nutrient deficiency can lead to duller-looking hair. OLAPLEX products repair important bonds in the cuticle, restore lipids, hydrate, and moisturize for beautiful, healthy shine & sheen.

Strong bonds support healthy porosity, helping hair maintain the right balance of moisture and reducing frizz. A well-maintained cuticle helps hair retain moisture more effectively, supporting the health of all textures – whether straight, wavy, curly or coily – by reducing frizz and maintaining balance. OLAPLEX products repair and protect bonds while supporting cuticle health and moisture levels.

The perception of softness varies for each individual. Healthy hair maintains an optimal balance of moisture and lipids, helping it feel nourished across textures. Hydration plays a key role in all hair types, preventing limpness in straight and wavy hair while supporting deeper moisture retention and elasticity in curly and coily textures. Factors such as heat styling, environmental stress, and product buildup can strip moisture, leading to dryness. OLAPLEX products help restore hydration and reinforce bonds to support overall hair health.

The distribution of disulfide bonds and follicle shape determine hair’s pattern (straight, wavy, curly, coily). When these bonds are strong and intact hair retains its form. Defined shape is a sign that bonds are strong and healthy. OLAPLEX Bond Building Technology™ and Bond Shaping Technology™ work deep within the hair shaft to reinforce and reshape hair’s foundational structure, allowing all hair types to hold their pattern.
