  1. Introduction to hair structure and biology, and to hair claims substantiation

  2. Introduction to hair product science and how hair products work

  3. Hair Claims Testing Methods


Those who attend TRI in-person will also have the opportunity to attend the ‘TRI Laboratory demos’ session on the final afternoon, as well as a barbeque on the first evening at TRI HQ.
