The Friday morning plenary lecture was given by Alan Swift entitled “Milestones on hair structure from 1665 to the present day.” Additional lectures were given by Trefor Evans of T.A. Evans LLC with “Changing the bulk properties of hair by non-reactive means;” Kyohei Joko of Sugiyama Jogakuen University with “The role of hydrogen bonding on permanent set of human hair-New Japanese hair straightening;" Joel Coret of TRI Princeton with “Effect of organic acids on hair fiber mechanical properties;” Marianne Brandt of proDERM with “Assessment of hair breakage from combing: Which procedure simulates best the true life situation?;; Veronique Maurin of Symrise, with “Microalgae: a sustainable source of innovative active for hair loss prevention;” Sylvie Bouzéloc of Dow Corning with “New approach for quantification of hair frizz;” Sebastien Breugnot of Bossa Nova Technologies with “Recent advancements in hair visual appearance evaluation;” and Franz Wortmann of the University of Manchester with “Considerations of a consistent model for the reflection of light from human hair.”
The topic of hair frizz–along with its causes, measurement and possible alleviation–was a reoccurring topic in a number of presentations. Of particular interest was work outlined by Steven Breakspear that ascribed cuticle thinning and removal as being the cause behind stray, frizzy flyaway fibers. In short, the localized bulk shape of the hair was believed to change in the absence of this outer reinforcing structure. This flies in the face of another somewhat controversial idea that the hair shape is dictated by differing ratios of ortho and para cortical cells. Advocates and opponents of this theory were present in the audience and a spirited discussion was had by all. The 19th International Hair Science Conference will be held in two years in Trier, Germany on Sept. 2-4, 2015.
