Preservatives & DMDM
Similar to other cosmetic brands in the industry, we use certain ingredients when necessary to help preserve the quality of our products. Otherwise, our products could grow moldy, change color, or start to smell.
Select TRESemmé products use DMDM hydantoin (dimethyl-dimethylhydantoin) as a stabilizing preservative. Industry regulators have approved this ingredient for use in personal care products to prevent harmful growth of bacteria and mold. Experts like the independent US Cosmetics Ingredient Review Panel and Europe’s Scientific Community on Consumer Safety have repeatedly found DMDM hydantoin to be a safe and effective cosmetics preservative.
For more information on DMDM hydantoin safety, please reference the following third-party resources:

Nonetheless, by July 2021, all TRESemmé products will be DMDM hydantoin free. To see if your Tresemmé product contains DMDM hydantoin, please refer to our ingredient labels, which differ for each product.
