Olaplex No. 4 Bond Maintenance Shampoo 250ml is used for cleansing and restoring hydration to damaged hair. This is a highly moisturising, sulphate-free reparative shampoo. Designed with patented Olaplex bond builder technology, this shampoo helps support the repair of broken disulfide bonds that can occur during chemical treatments such as colouring, perming, or straightening. Each application may nourish and strengthen the hair, leaving it healthier, shinier and more manageable. Key ingredients like Bis-Aminopropyl Diglycol Dimaleate work to fortify hair structure, while Sunflower Seed Oil and Fermented Argan Oil provide essential moisture and shine. Ideal for all hair types, this shampoo ensures that hair remains vibrant and protected, making it an essential part of your daily hair care routine.
