Olaplex No. 5 Leave-In Moisturize & Mend

Olaplex is a high-performance hair care brand founded in 2014 by Dean Christal in Santa Barbara, California. The brand gained global fame for its patented bond-building technology, which repairs disulfide bonds in hair that are broken by chemical, thermal, or mechanical damage. The No. 5 Leave-In Moisturize & Mend is a relatively new addition to their lineup, designed to provide long-lasting hydration and seal split ends using their signature chemical science combined with nourishing ingredients like squalane and murumuru butter.

Manufacturing of Olaplex products primarily takes place in the United States, utilizing a capital-light, outsourced manufacturing model. In terms of ownership, the brand underwent a significant transition when it was acquired by the private equity firm Advent International in 2019, followed by an IPO in 2021. As of early 2026, there have been reports of interest from large consumer goods companies like Henkel, but Olaplex Holdings, Inc. remains a publicly traded entity with Advent International as a major shareholder. The brand continues to be a staple in professional salons and specialty beauty retailers worldwide.
