Testing the efficacy of hair care products

We offer a wide range of biophysical test methods for determining the efficacy of hair care and hairstyling products, as well as for carrying out corresponding claim support studies. In our specially equipped hair laboratory, we investigate conditioning, strengthening, and protective product properties. The different methods can also be combined here. In addition to the biophysical methods, we also offer in vivo proof of efficacy such as anti-dandruff studies and studies for products that are supposed to promote hair growth.
