What Else You Need to Know: The Olaplex No. 4 Bond Maintenance Shampoo is more than a cleanser — it is an active hair repair treatment in shampoo form. Powered by Olaplex's patented bond-building technology and a gentle blend of coconut oil-derived surfactants, it nourishes and hydrates while repairing the internal bonds that give hair its strength and resilience. Vegan and cruelty-free, it pairs perfectly with the Olaplex No. 5 Bond Maintenance Conditioner for a complete bond-building wash day routine.

Why It Works — Key Ingredients:

• Coconut Oil-Derived Surfactants: A gentle, hydrating cleansing base that removes dirt and buildup without stripping the hair's natural moisture or disrupting its internal bond structure.
• Glycerin: A powerful humectant that draws moisture into the hair shaft and locks it in, delivering immediate softness and hydration that lasts well beyond the shower.
• Behentrimonium Methosulfate and Cetearyl Alcohol: Conditioning agents that smooth the hair cuticle, reduce frizz, and improve manageability, leaving hair feeling silky and detangled after every wash.
