This includes any hydrolyzed protein from wheat, rye, barley or oats, which may contain gluten.

No, we do not use formaldehyde as an ingredient in any of our products. However, a few formulas use ingredients that release trace amounts of formaldehyde as they work to keep the product fresh, and keep harmful bacteria out. Regulators and scientific experts across the globe agree that such small amounts of formaldehyde do not cause any harm. In fact, you are exposed to a larger amount of formaldehyde when you eat a pear.

There are no recalls on any TRESemmé products. All our products meet the highest global safety standards and are safe to use. If you are experiencing an issue with a product, our Consumer Services team is here to help you, and you can get in touch with them here.
