May 2019 in “Cosmetics” This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.
18 citations
,
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.
