Latest Developments in Hair Claims Substantiation Methods – Webinar Wednesday 22 February



Hair testing experts Dr Paul Cornwell and Eleanor Lehman (TRI Princeton, USA) will focus on claim substantiation tests for our next webinar on Wednesday 22 February. They’ll also be sharing exciting new test methods that you won’t want to miss!

“If you can not measure it, you can not improve it” is a quote attributed to the famous British physicist Lord Kelvin (1824-1907). This quote remains relevant today when dealing with claims substantiation techniques for hair care. In order to make new or stronger claims, you always need better measurement techniques.

This presentation will describe the four main types of claim substantiation tests used in hair:

  1. Sensory tests
  2. Tress tests,
  3. Single fibre tests
  4. Tests for investigating the chemical composition of the hair

It will then review several exciting new developments in this area made at TRI, including new assays for hair porosity, hair breakage and hair lipid composition, and new test methods developed for use on very curly, textured hair.
