From Fiber Chemistry to Innovation Gaps: Rethinking Hair Science for Diverse Hair Types
Frick Chemistry Laboratory
Thursday, February 5, 2026
Mixer and refreshments 6:00 - 6:30 pm
Seminar and Discussion 6:30 – 8:00 pm
Abstract
Human hair is often treated as a simple cosmetic substrate, yet from a chemical perspective, it is a highly complex, hierarchical biomaterial whose performance depends on the interplay of proteins, lipids, water, and external stressors.
This lecture will present an overview of hair science through the lens of its key constituents - proteins, lipids, pigments, and water, and how they govern fiber structure, properties, and performance. This talk will examine how chemical, thermal, and environmental stresses alter these components, leading to changes in mechanical behavior, surface properties, and perceived hair “quality,” as well as the protection strategies currently used to mitigate such damage.
Finally, the lecture will outline several opportunity spaces where chemists - particularly those with backgrounds in polymers, protein design, lipids, and interfaces - may find compelling avenues for innovation and entrepreneurship aimed at improving hair quality and longevity across diverse populations.
Bio Sketch
Dr. Ernesta Malinauskyte earned her PhD in Chemical Engineering at Kaunas University of Technology (Lithuania). Currently, at TRI Princeton, in the role of Hair Research Director, Ernesta leads a team of results-driven, and passionate researchers investigating how hair chemistry influences hair mechanical properties and fiber interactions with hair care, chemical & physical treatments, and environmental insults. In the ever-evolving landscape of hair care technology, hair research team pushes boundaries, developing claims substantiation methods that set new standards for the industry. The aspirations of the team also extend into diverse domains, such as analytical sciences, textiles, and even venturing into nail and skin cosmetics.
Ernesta is an active research community member via publishing and giving presentations on research and hair science topics in academic environment, industry, and hairdresser communities. She also serves on the editorial board of the International Journal of Cosmetic Science.
Reservations required. The event is free and open to the public.
