Efficacy studies for hair care products
Our hair laboratory offers a wide range of biophysical tests to determine efficacy of hair care and hair styling products. The spectrum ranges from combing force tests for demonstrating conditioning effects through tension measurements for the determination of hair repair effects to measurement methods that demonstrate styling effects such as curl retention or volume determination.
Since each test design examines a special feature, different methods can also be combined. For example, the combination of combing force on wet hair can be combined with a flexibility test on dry hair to get a comprehensive proof of efficacy.
In addition to biophysical methods, proDERM Cosmetics also offers in-vivo demonstration of efficacy such as hair shine testing using a panel test, anti-dandruff studies and of course studies to investigate the hair growing potential of cosmetics.
