Olaplex No 4 Bond Maintenance Hair Shampoo For Repair, Strength & Nourishment 250ml

Olaplex N°. 4 Bond Maintenance Shampoo is a highly nourishing and reparative shampoo developed with patented Olaplex Bond Building technology to effectively cleanse, hydrate and protect the hair. It contains an active ingredient Bis-aminopropyl diglycol dimaleate that works at molecular level to dramatically improve the hair strength, repair damage and protect the hair. It strengthens and adds shine to damage-prone hair as it gently cleanses. Hair is made up of the fibrous protein, keratin and held together by bonds. Hydrogen and salt bonds are physical bonds and are easily reformed by changes in pH, water and/or heat. Disulfide bonds are chemical covalent bonds. These bonds cannot be broken by water. Millions of disulfide bonds give hair its structure, strength, and stability. When hair subjected to heat styling, color or chemical treatment, sometimes brushing & tugging or due to weather may lead to breakage of these disulfide bonds. When these disulfide bonds are broken, hair is damaged and can appear dry, frizzy, and brittle. Olaplex No.4 Bond maintenance color safe shampoo works in a unique way to repair broken bonds and restore healthy hair quickly and effectively. The rich lather nourishes and repairs to leave hair smoother and more manageable. It is recommended to pair with No.5 Olaplex conditioner for softer, shinier, healthier-looking hair with every wash. Study showed that 90% smoother, better detangling, more conditioned and 49% reduction in breakage after the use of Olaplex No.4 Bond maintenance shampoo.
