What we test for you
Shampoo
Determination of the product properties of a wide variety of shampoos by half-side comparison and subsequent assessment of the properties for your claims.
Anti-Dandruff
To test the efficacy and tolerability of anti-dandruff products, the finished formulations are tested on volunteers with dandruff.
Hair colours
Application and colour results on the test bench: Hair colours are tested directly on test persons or in laboratory tests on hair strands.
Conditioner
Properties for your hair care product: Hair shine, volume, heat and UV protection are some of the many claims a hair care product can make.
Case studies
In our Institute for Hair Physiology, application studies of all kinds are carried out in the hair area combined with dermatological and ophthalmological control as well as on hair braids and in the laborator.
Here, standardized measurements of a wide variety of parameters take place to document the effectiveness and tolerability of hair care and hair styling products:
Documenting and preparing your data
At Institut Dr. Schrader, the documentation and preparation of your data is always included in your order. You will receive your data as a detailed and scientifically sound test report.
Statistical processing of all study data / bio-statistics
Matching study designs and claims support for skin testing can be found here.

You are looking for the appropriate efficacy test for your product. Here you will find some suggestions. Individual adaptations are possible at any time.
Digital Measurement
Volume, Smoothness, Anti-Frizz
Digital volume measurement is used to determine hair volume following the application of hairstyling or hair care products. For this test, hair strands are treated differently depending on the type of product.
A light source is used to cast a shadow of the hair strands, which is measured digitally before and after treatment (possibly several treatments). The exact volume of the hair strand is determined by rotating the strand and further image analysis.
