Principally the course, which will take place in Princeton, New Jersey, in April, will cover the most recent findings concerning hair fiber structure and morphology, in turn helping to develop a fundamental background for specific characterization methods necessary for effective products. TRI/Princeton , which focuses on research into textiles, but has more recently expanded into fibers and the hair care market, will highlight technologies that provide quantitative measurements of the effects of a variety of treatments. In doing so, the course will look at microscopic and optical techniques, including microfluurometry, UV-microspectrometry, as well as the use of light scattering devices, known as Goniophotemetry. The machinery also includes mechanical tests, including Multistation Fatigue Apperatus and a Combing Maching; as well as Physical Chemistry of Approaches demonstrations that will focus on Wettability, Vapor Absorption and Spreading Behaviour of Viscous Material. The course is specifically aimed at hair researchers and those developing hair care products, together with individuals involved in the claim substantiation of products, as well as marketing. Highlights will include three principal areas: hair structure, products and their interaction with hair and hair appearance. Insight on hair structure will include latest research on Keratin fibre, hair assembly properties and hair mechanochemistry. The focus on how products interact with hair will look at UV and hair damage, effects of cosmetic treatments on fiber surface and an overview of formulations and actives. Finally, hair appearance will look at optical properties – light scattering and luster, as well as hair appearance and hair body. Moderated by Dr. Peter Kaplan, research director for TRI personal care, the course will include guest speakers such as Dr. Yash Kamath, cosmetic chemistry consultant; Dr. Clarence Robbins author of a globally published book on hair science; and Dr. K. Ramaprasad, TRI senior scientist in spectroscopics. Registration for the course should take place by March 27 and costs $1495 for members, with a $100 discount for members.
