Olaplex No. 4 Fine Bond Maintenance Shampoo is an ultra-lightweight formula specifically designed for fine hair. It gently cleanses while removing residue, providing immediate root volume without weighing hair down. Enriched with flexible polymers, low molecular weight hyaluronic acid, and a hydrating matrix, it strengthens the hair fiber, moisturizes, and prevents future damage. Clinically, it doubles hair volume and strength while reducing breakage by 60% when used with No. 5 Fine Conditioner. Use is simple: apply to wet hair, lather, rinse, and then follow with the conditioner.
