The Fabric Factor: The Role of Your Pillowcase and Hair Accessories in Hair Care
TRI Princeton's recent studies by Dr. Ernesta Malinauskyte, Dr. Xuzi Kang, and Dr. Marcella Gabarra illuminate the subtle yet significant ways that common materials interact with our hair, providing concrete data to support claims about the gentleness of various materials on hair.
Aqua-Mane-ia IV: The Science and Art of Water on Your Hair
Summer: the sun, the sea, the pool, the daquiris….and the green hair….an affliction that usually affects blondes and often occurs from swimming in a pool. The technical term for green hair is chlorotrichosis, and, contrary to urban legend, it is the interaction between hair and copper salts that cause the green color rather than between hair and chlorine.

Beyond the Tube II: Exploration of Lip Hydration and the Impact of Lipsticks on Moisture Retention
Lips, those soft bits on our faces, do a lot more than help us chat or smile. They're different from the rest of our skin, which means they need a little extra love and care. If you're someone who loves lipstick, it's even more important to know more about the uniqueness of our lip skin.

Exploring the Potential of the Three-Point Cantilever Bending Test
Dr. Xuzi Kang's studies have shown that the three-point bending test can measure the effects of damage on hair softness, and open new opportunities for damage repair claims. Her work has also shown that the technique can measure the degree of set delivered by different styling products and their resistance to humidity.
