October 2014 in “Langmuir” This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.
This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

January 2009 in “Colloids and Surfaces B: Biointerfaces” This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

April 2010 in “Langmuir” This study found that human hair surfaces exhibit nonhomogeneous wettability, potentially influenced by daily rhythms and even monthly changes possibly linked to the menstrual cycle.
