As of my last update, Olaplex hadn't released a product named "Olaplex Broad Spectrum Chelating Treatment." However, Olaplex is known for its innovative hair care products, particularly those focused on repairing and strengthening damaged hair through their bond-building technology.

Chelating treatments in hair care are designed to remove mineral buildup and impurities from the hair, often caused by hard water or certain hair care products. While Olaplex hasn't specifically marketed a product under this name, it's possible they may have introduced a new product or treatment since my last update.

For the most accurate information, I recommend checking Olaplex's official website or contacting them directly to inquire about any new products they may have released, including a potential Broad Spectrum Chelating Treatment.
