In summer, three chemical agents act simultaneously on the hair fiber: UV radiation (photo-oxidation of melanin and protein chains), chlorine (oxidizing agent that degrades disulfide bonds), and sea salt (high hygroscopicity that fragments dry cuticles). Hairswiss explains the degradation mechanisms and relevant protective actives.

The Three Hair Types: Molecular Basis of Hair Fiber Curvature and Formulation Implications
Hair types (straight, wavy, curly) are not an aesthetic classification: they reflect the elliptical shape of the follicle and the asymmetric distribution of disulfide bonds in the cortex. This geometry directly influences porosity, mechanical resistance, and response to cosmetic actives. Hairswiss explains the molecular basis of hair curvature and its implications for formula selection.
