What’s in Nᴼ.4 Bond Maintenance® Shampoo?

The ingredients in a single bottle of Nᴼ.4 Bond Maintenance® Shampoo makes the shampoo a one-stop shop for well-rounded, healthy hair, starting with OLAPLEX’s patented Bond Building Technology™. OLAPLEX developed and patented Bis-Aminopropyl Diglycol Dimaleate, which became the first ingredient of its kind in the bond builder category. This innovative ingredient protects, nourishes, and restructures hair internally by repairing bonds on a molecular level. To soften, nourish, and moisturize hair, this shampoo contains ingredients like: 

• Coconut oil-derived surfactants: Provides an easy lather that leaves the scalp and hair feeling hydrated. 
• Glycerin: This ingredient comes from plant oils and pulls moisture from the air into the hair, improving hydration and softness. 
• Helianthus annuus (sunflower) seed oil: This emollient adds shine, reduces moisture loss, and smooths the hair.
• Musa sapientum (banana) fruit extract: Boosts moisture retention to condition and soften hair.
• Prunus armeniaca (apricot) kernel oil: This lightweight emollient adds softness without heavy buildup.
• Pseudozyma Epicola/Argania Spinosa Kernel Oil Ferment Filtrate (fermented argan oil): Tames and smooths frizz and flyaways. Why is it fermented? Fermenting the oil lowers the pH level which helps close cuticles helping them to lay flat. Fermented oils contain more potent vitamins and nutrients and have better absorption rates compared to non-fermented oils.
• Panthenol (Vitamin B-5): Penetrates the hair shaft to help hair feel thicker and improve elasticity.
