Frequently Asked Questions
Our products may contain animal-derived ingredients from normal sustainable animal husbandry or farming or fishery practices such as milk, honey, lanolin, silk etc. Products may also contain processed and denatured animal by products with established uses such as tallow, keratin, collagen, elastin etc. In most cases, this is because the ingredient performs a function for which there is no suitable alternative available. Animal welfare is an important social and ethical issue. As part of our Sustainable Agricultural Code, we work with suppliers to continuously improve the sourcing of agricultural ingredients.
TRESemmé is committed to eliminating animal testing across the business. Since the 1980s, TRESemmé has remained at the forefront of research into non-animal approaches to assess product safety and advocates effective, science-based regulation on alternatives to animal testing that ensure consumer safety and facilitate innovation.
TRESemmé scientists play a leading role internationally, working with key academic, government and NGO scientists to lead the development and application of non-animal tested approaches for assessing consumer safety. Where we are legally obliged to commission animal studies, we ensure a minimal number of animals are used.
No animal testing is carried out in our own laboratories. In countries where local authorities test our products on animals, we are working with government scientists to help implement non animal-based methods.

We are committed to improving the sustainability of our products and are on a journey to towards reducing our environmental footprint and minimising our impact on the planet.
At TRESemmé, we always make sure to only select and use professional-quality ingredients in our products. Each and every ingredient is rigorously screened by our team of scientific experts before it goes into our shampoos and conditioners. This commitment to safety never ends, and we are continually improving our products and checking the latest science to make sure they meet the highest standards in quality and safety.
You can find the ingredients list for each TRESemmé product on the individual products page. If you are looking for more detailed information, you will find the ingredients lists for each product sold in Europe within our home and personal care brands get details.
We also tell you about how our products are developed and describe the careful steps we go through to make sure that they are safe for you, your children and the environment. If we have left any questions unanswered, please get in touch with us.
We do not use formaldehyde in our products. We do use formaldehyde donors such as DMDM hydantoin in some of our shampoos and conditioners. Formaldehyde donors release low levels of formaldehyde throughout the shelf-life of a product, which protect the product from spoiling. Formaldehyde is a natural substance which is present in food and produced within our bodies, and the low levels present in our products are well within safe and regulated levels. This has been confirmed by regulators and scientists around the world.
Leading industry scientists and regulators agree that DMDM hydantoin is safe for use and should not cause hair loss. The ingredient is widely used throughout the beauty industry to prevent harmful growth of bacteria and mould. Whilst we use this ingredient in select TRESemmé formulas, none of our products in the UK & Ireland contain DMDM hydantoin.
Our products meet the highest global safety standards, are safe to use, and should not cause hair loss. Hair loss can occur for many reasons including hormonal changes, stress, genetic makeup, pregnancy, serious illness, medication, diet, and hair styling techniques. And, as with any topical product, people may have sensitivities to a range of ingredients, natural or otherwise, so if you are experiencing an adverse reaction, please stop using the product and consult your doctor.
