Designed to be used weekly in place of your regular shampoo, the Olaplex No. 4C Bond Maintenance Clarifying Shampoo delivers a deep cleanse. The formula uses an advanced broad-spectrum clarifying system to remove a wide array of impurities, including hard water minerals, chlorine, heavy metals and product build-up, while resisting stripping or drying out hair. Supported by patented Bond Building Technology™, the shampoo leaves hair feeling touchably soft and optimally prepped for the next steps in your Olaplex routine. Suitable for all hair types. Vegan.
