November 1984 in “Journal of Colloid and Interface Science” The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.
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 2004 in “PubMed” This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.
March 2026 in “Journal of the mechanical behavior of biomedical materials/Journal of mechanical behavior of biomedical materials” In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.
