For every TRESemmé product we develop, we start with key insights about the most sought-after salon trends and develop unique formulations that deliver on performance and quality. Before making our products available to consumers, we make health and safety our top priority. That’s why all TRESemmé formulas are rigorously assessed by leading experts using industry-proven methods before being made available in market. We ensure that our products meet the highest standards in quality and safety, respecting all applicable laws and regulations in the United States, Europe, and all other markets where TRESemmé is sold.
Standard evaluations we conduct on our products prior to going to market include
- Stability testing: testing done to ensure that consumers will get a quality product that is safe and stable for use under different temperature and humidity conditions.
- Safety assessments: a review of what ingredients are used in every formulation and in what quantity. This helps make sure that we only use what is needed to provide safe and effective products.
- EcoDesign review: review of environmental impact and compliance with sustainability targets.
- Microbiological testing: tests that the product is preserved for the duration of its shelf life. This ensures that no microorganisms, bacteria, and mold are growing in our products.
- Regulatory assessment: ensures that our products, their ingredients, how it is manufactured and labeled comply with all federal and state laws.
- Fragrance testing: consumer or expert panel testing on any new fragrances used within our products
All of these assessments and evaluations prove that TRESemmé products are safe to use.
In addition, we commonly test our products for efficacy to ensure they deliver the top-tier results our consumers expect. Examples of these testing methodologies include:
- Double-blind testing against competitors assessed by professional stylists and consume
- Technical instrumental testing to ensure performance
- At-home user testing with 100+ participating consumers
Result: TRESemmé products perform as well or better than salon brands
