According to the 49-page case, TRESemmé Keratin Hair Smoothing Shampoo and TRESemmé Keratin Smooth Color Shampoo, made by defendants Unilever United States, Inc. and Conopco, Inc., contain a preservative called DMDM hydantoin, which is known to leach formaldehyde when it comes into contact with water.
Given formaldehyde is a “well-known human carcinogen” that can cause cancer and other harmful reactions when absorbed into the skin, Unilever’s use of DMDM hydantoin in the TRESemmé Keratin Smooth products is “an entirely unnecessary risk” since safer and natural alternatives exist, the lawsuit argues.
Nevertheless, the suit alleges, the defendants have failed to properly warn consumers of the risks associated with using such a strong chemical on their hair and have even gone so far as to claim the TRESemmé Keratin Smooth products are safe.
“Defendants continued to conceal the dangers of the Products by failing to appropriately and fully recall the Products, by continuing to claim the Products were safe when properly applied, and by failing to warn consumers of the dangers attendant to the Products’ use,” the complaint scathes.
The lawsuit alleges Unilever marketed its “Keratin Smooth” line of shampoos to women who “wanted smooth, shiny, manageable hair with no frizz.” Through online marketing and the products’ labeling, the defendants allegedly represented that the TRESemmé products contained keratin, a protein found naturally in hair, and would “deeply nourish,” “gently cleanse,” and “repair hair.”
According to the case, however, Unilever failed to warn consumers that a preservative named among the products’ ingredients has been known by the defendants to cause or contribute to hair loss and scalp irritation. The suit charges that nowhere on the products’ packaging or in advertising did Unilever warn customers of the risks of using DMDM hydantoin on their hair and scalp and instead claimed the shampoo was safe when properly applied.
The lawsuit explains that DMDM hydantoin is a formaldehyde donor, which is a class of preservatives added to water-containing cosmetics to prevent the growth of microorganisms through the release of small amounts of formaldehyde. According to the case, the defendants until recently used the chemical in their TRESemmé Keratin Smooth line since keratin is a protein—i.e., a food for microbes—and has a limited shelf life.
Per the complaint, the use of formaldehyde donors, and particularly DMDM hydantoin, in cosmetic products has been linked to the development of allergies, dermatitis, hair loss and even cancer. The U.S. Food and Drug Administration, the suit says, considers DMDM hydantoin to be one of the top allergens “that cause the most allergic reactions from the use of cosmetic products,” especially since individuals can become more sensitive to the irritant over time. The case adds that irritation of the scalp is linked to hair brittleness and hair loss.
According to the suit, Unilever has known of the dangers associated with DMDM hydantoin for a decade or more given the chemical and several other ingredients were the subject of prior litigation against the company. Per the case, Unilever’s Suave Keratin Infusion product, which was advertised as formaldehyde-free, was recalled in 2012 following complaints of hair loss and scalp irritation. The lawsuit initiated against the company resulted in a $10.2 million settlement that was upheld by an appeals court in 2016, the suit says.
Though Unilever continued using DMDM hydantoin as a preservative and even publicly asserted that the chemical was safe for use in hair products, the company only recently reformulated its TRESemmé Keratin Smooth shampoos to replace DMDM hydantoin with other preservatives, the case avers.
Given the litigation against Unilever, not to mention the flood of consumer “horror stories,” some of which are cited in the lawsuit, the defendants should have been well aware of “the high potential for toxicity or allergic reaction” caused by use of the TRESemmé Keratin Smooth products, the lawsuit charges. Nevertheless, the company has allegedly “failed and continues to fail” to warn consumers about possible reactions and has even attempted to downplay or conceal the plethora of consumer complaints.
“Unilever continues to this day to advise consumers that these Products are safe to use as directed, without providing any disclosure concerning the complaints of hair loss and with no warnings regarding the hair loss that may result from their continued use,” the complaint reads. “Indeed, despite Unilever’s knowledge and awareness of hundreds if not thousands of complaints of significant hair loss and breakage caused by the Products, Unilever continues to claim the use of DMDM hydantoin it [sic] is safe and permits them to be sold to this day — without providing consumers with any revised warnings or disclosures.”
According to the suit, the defendants’ “reckless indifference” has allowed Unilever to realize “sizeable profits” at the expense of consumers.
