The In-depth Examination of the Science of Hair and Hair Care Products for Professionals in the Hair Fiber and Cosmetics Industries

Course Highlights Include

Hair Structure and Biology

Hair – Product Interactions

About the Course

Moderated by TRI Adjunct Research Fellow, Dr. Trefor Evans, this course is an in-depth examination of the science of hair and hair care products.

The instructors approach the material from a fundamental perspective, offering students the opportunity to closely examine the basic structure of hair, of hair care products, and interactions between the two. The style of this course is a unique approach which provides researchers with the fundamental scientific principles important to the hair care industry. Participants will gain knowledge and understanding of the principles of hair and hair product interactions; thereby enhancing their skills for future research.  Demonstrations will be used to provide an in-depth approach to explaining techniques.

The class size for all TRI courses is limited in order to provide all participants with an intense, personalized learning environment.  Additionally, it is TRI’s intention to foster networking amongst researchers in the field, and time is built into the course to allow for this value-added opportunity.

This is the right course for people working in research and development in technology-based innovation, including but not limited to:

Trefor Evans: With a background in the areas of Analytical Chemistry and Measurement Science, Trefor has spent the last 20 years applying these disciplines to a variety of roles within the hair care industry. This includes Award-winning research in the area of fundamental hair science; but also involves support and participation in the launching of successful hair care brands, and many different products worldwide. Such activities were predominantly performed in the Product Development laboratories of Helene Curtis and Unilever, where Trefor managed a group of instrumental testing laboratories addressing such diverse issues as claim substantiation, product development support, manufacturing support and problem solving. Today as and independent consultant and Adjunct Research Fellow at TRI, Trefor utilizes his background to help client companies develop new and improved hair care products.

Jim Anderson: Jim is a Connecticut-based consultant advising both cosmetic ingredient manufacturers and finished product producers on ingredients and formulae. His extensive knowledge of the chemistry, synthesis, and properties of cosmetic ingredients was gained from 23 years of hands-on organic syntheses. Additionally, he has more than seven years experience in designing and specifying materials to meet or exceed all performance and international regulatory requirements. He has 30+ years in the cosmetic industry, and has worked for both Bristol-Myers Squibb and Procter & Gamble.

Robert Lochhead: Dr. Lochhead currently serves as a professor at the School of Polymers and High Performance Materials at the University of Southern Mississippi; he was Chair and Director of the Polymer program from 1993 -2013. Prior to joining academia, the first twenty five years of his career were dedicated to industrial research that ranged from polymer and silicone synthesis to colloid and surface science and hydrophilic polymers. Dr. Lochhead is the author of more than a hundred scientific papers and reviews, and a named inventor on 22 patents. The polymers that he has invented have enabled new and better technologies with beneficial societal and environmental impact. Dr. Lochhead has received many awards for his contributions including The SCC’s Maison G. DeNavarre medal; The American Institute of Chemists’ ‘Chemical Pioneer Award’, and the Education Award from the Society of Plastics Engineers. Dr. Lochhead serves on the INCI committee and he has served twice as the President of the Society of Cosmetic Chemists, and President of the International Association of Formulation Chemists.

Roger McMullen: Roger L. McMullen, Ph.D. is currently a Senior Research Scientist in the Materials Science Department at Ashland Specialty Ingredients.
