🇺🇸Olaplex

American bond-building haircare brand founded in 2014 by chemists Dean Christal and Craig Hawker. Olaplex's core technology — bis-aminopropyl diglycol dimaleate — works by relinking broken disulfide bonds within the hair shaft, repairing structural damage caused by chemical services, heat, and mechanical stress. The brand launched into professional salons before expanding into retail, and is now one of the most recognised names in damaged-hair repair globally. Products are numbered rather than named (No.0 through No.10), with each step designed to slot into a different point in your routine. The caveat for curly hair: most Olaplex products (No.3–No.8, No.6) contain silicones, making them incompatible with a strict Curly Girl Method routine — though they work well for curlies who follow a modified approach. Three products stand out as CGM-friendly: No.9 Bond Protector Serum, No.10 Bond Shaper Curl Gel, and No.5 Leave-In, all confirmed silicone-free by the brand. Olaplex is widely available in the UK via Boots, LookFantastic, Cult Beauty, and Space NK. The brand is NYSE-listed (OLPX) following a 2021 IPO.
