Heads-up study of hair dynamics may lead to better hair-care products

From frizzy perms to over-bleached waves, "bad hair days" could soon become a less frequent occurrence. Chemists report the first detailed microscopic analysis of what happens to individual hair fibers when they interact with each other, an advance in knowledge key to the development of improved shampoos, conditioners, and other products for repairing damaged hair, the researchers say.
Embracing that adage, "Personal care begins with hair," consumers now spend almost $60 billion annually on hair care products, one of the personal care industry's largest market segments. Despite the increasing availability of new hair care products within the past century, many products are inadequate for tackling today's rigorous hair treatments, the researchers say.
"For the first time, we present an experimental setup that allows measuring the subtle forces, both physical and chemical, that arise when single hairs slide past each other or are pressed against each other," says study co-author Eva Max. "The findings will help provide clearer strategies for optimizing hair care products." MTS
