Olaplex No 4c Bond Maintenance Clarifying Shampoo is a professional cleansing formula designed to remove accumulated impurities from hair and scalp. This 1000 ml bottle provides a deep-cleansing treatment that eliminates product residues, environmental pollutants, and other hair-dulling substances without stripping natural moisture. The sulfate-free formula contains bond-building technology that helps maintain hair structure while clarifying. It effectively removes impurities that can lead to damage and breakage, restores natural shine, and improves hair texture. The shampoo is suitable for dull, discolored, dry, unmanageable, or oily hair. For optimal results, apply from the hairline, work through lengths and ends to create lather, and then rinse thoroughly. Use once a week or every two weeks instead of regular shampoo as part of a care routine. Follow up with Olaplex No 5 Bond Maintenance Conditioner for complete hair care. The formula includes moisturizing ingredients to prevent dryness during the deep-cleansing process. This clarifying treatment helps maintain healthy hair by removing residues that can affect hair quality and appearance. The product is available in a 1000 ml container, offering a long-lasting supply for regular care treatments.
