A class action suit has been filed against Johnson & Johnson’s (J&J) OGX brand shampoos and conditioners due to speculated scalp irritation and hair loss. The products are marketed to nourish, smooth and revive hair but according to Plaintiff Larissa Whipple, the products “falsely represent” those claims with their combination of ingredients including DMDM hydantoin, which has previously been alleged to cause hair loss and scalp irritation upon contact with water. Previous DMDM Hydantoin Allegations A previous suit was filed against Unilever/Conopco for its DMDM hydantoin-containing TRESemmé Keratin Smooth Color Shampoo, to which industry expert Perry Romanowski, a consultant and former formulator on the TRESemmé brand, responded, "...There is zero scientific evidence to indicate DMDM hydantoin would cause any hair loss."
