It seems there may be a misunderstanding or a hypothetical product you're envisioning. As of my last update, Olaplex hasn't released a product specifically named "4-IN-1 Moisture Mask & Broad Spectrum Chelating Treatment." However, Olaplex is known for its range of hair care products focused on repairing and strengthening damaged hair.
Their lineup typically includes items like the No. 3 Hair Perfector, No. 4 Bond Maintenance Shampoo, No. 5 Bond Maintenance Conditioner, and others, which aim to restore and maintain hair health.
If this product exists or has been released since my last update, I suggest checking Olaplex's official website or verified retailers for accurate details on its features and benefits.
