Recently, six women in the US filed a lawsuit against Unilever because they experienced hair loss, thinning hair, allergic reactions, and other scalp side effects after using TRESemmé shampoo or conditioner. The six plaintiffs claimed that the DMDM acetylurea preservative used in TRESemmé's hair care products would cause these side effects. The ingredient was involved in a similar storm more than 10 years ago, and Unilever knew it was the culprit. The brand has already entered China and was endorsed by singer Li Yuchun and actor Jiang Xin. According to the customer service of the JD Global Shopping Platform, the products it sells have no carcinogenic ingredients.
