The TRI hair course is an introductory course designed for graduate and post-graduate level cosmetic scientists who need to build their knowledge in hair science and claims substantiation.

Attendees should leave with an understanding of hair structure and biology, hair product science and the key measurement techniques used to test the performance of hair products and support hair claims.

All the course is given on-line and is available to attendees all around the world. Last year we had over 100 attendees, some joining us from as far away as South Africa, Australia and the Philippines.  

​

However, now we are past the worst of the COVID pandemic, we can open our doors to visitors for one day of the course. Attendees based in the US, or wanting to travel to US, will be able to visit the TRI laboratories on Friday 26th April. Visitors can view Day 3 of the lectures in the morning in our Seminar Room on a big screen (i.e. as a hybrid meeting), have a lunch with the speakers, and then have live demos of hair testing methods in the afternoon. There is no extra charge for the laboratory visit, but please make us aware that you wish to attend when you complete your registration. For safety reasons, places must be limited to 25 external attendees. It will be first come, first served.
