Hair Health Starts With the Scalp: Insights from Two P&G Head & Shoulders Experts
Hair care scientists scratched their heads for some time before they could put their finger on the primary causes of dandruff. Now, with the flakes brushed away, they are seeing the scalp in a new light. Two Procter & Gamble scientists, James Schwartz, Ph.D., and Rolanda Wilkerson, Ph.D., both with the Head & Shoulders brand, explain how in this exclusive interview.

Image Processing and Analysis to Evaluate the Effects of Porous Polyamide Microspheres in Cosmetics
Described here is an image processing system that compensates for changes in illumination and volunteer position, and two algorithms to quantify skin texture and wrinkles. These methods evaluate skin parameters from a single image without contacting skin. Their abilities are demonstrated here in evaluations of the benefits of porous polyamide ultra-fine powders on skin texture and gloss.
