Olaplex No. 5 Fine Bond Maintenance Conditioner is a lightweight, volumizing conditioner designed specifically for fine, fragile, or flat hair. The 1000 mL / 33.8 fl oz pump bottle provides a generous salon-size supply of this reparative formula.

Powered by Olaplex's patented Bond Building Technology, this conditioner works at the molecular level to reconnect broken disulfide bonds within the hair strand, restoring strength and resilience with every wash. Unlike the original No. 5, the Fine formula is engineered with a lightweight texture that delivers all the bond-building benefits without weighing fine hair down, helping to preserve natural volume and body.

Regular use strengthens hair against damage from chemical services, heat styling, and environmental stressors. The formula hydrates and smooths the hair cuticle to reduce frizz and improve shine while keeping fine hair feeling light and full. It is vegan and cruelty-free.
