Olaplex No. 4 Bond Maintenance Shampoo 250 ml is a professional restorative shampoo that repairs damaged, dry, and chemically treated hair from the inside out. Thanks to its patented Bond Building Technology™ , broken disulfide bonds in the hair are actively repaired – something standard shampoos can't do.
This original Olaplex shampoo is ideal for anyone looking for the best shampoo for dye-damaged hair , a shampoo that repairs broken hair , or an original Olaplex shampoo for stronger hair . The result: visibly less breakage, more shine, and noticeably stronger hair with every wash.
The active ingredient , Bis-Aminopropyl Diglycol Dimaleate, is a patented molecule that repairs broken disulfide bonds in the hair structure. These bonds, responsible for hair's strength and elasticity, are damaged by coloring, bleaching, heat, and mechanical stress.
Comparison with standard shampoos:
While regular shampoos focus primarily on cleansing and cosmetic softness on the surface, Olaplex No. 4 works deep within the hair fiber. This results in structural and long-lasting improvements to hair condition, rather than just temporary ones.

Founded in 2014 by two leading scientists, Olaplex has permanently transformed the professional hair industry with its patented bond-building technology. The brand was quickly embraced by top hairdressers, salons, and colorists worldwide.
Olaplex isn't a cosmetic care brand, but a scientifically driven hair repair concept. Its products are designed to address hair structural damage at the molecular level and are considered the gold standard in bond-repair hair care worldwide.
For the advanced user, Olaplex No. 4 stands out because it actively works on disulfide bonds in the hair cortex. Unlike protein- or silicone-based shampoos, Olaplex offers structural repair without hardening or overloading the hair.
In professional routines, No. 4 is used as maintenance after intensive treatments such as No. 1 & 2 or No. 3. When applied correctly, the shampoo contributes to long-term improvements in hair strength, elasticity, and resistance to future damage.
