Denatured Alcohol (Alcohol Denat., ethanol C2H5OH, MW 46 Da) is a short-chain, volatile and water-miscible alcohol whose drying effect on the hair fiber results from the solubilization of intercuticular lipids and surface water entrainment by evaporation. Hairswiss analyzes its chemistry, problematic concentration thresholds and professional formulation alternatives.

Summer Hair Protection: UV, Chlorine and Sea Salt — Degradation Mechanisms and Protective Actives
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.
