Disulfide Bond Protection Systems Vs Amino Acid Protector: Comparative Analysis in Real Salon Practice
Abstract
In the context of contemporary aesthetic trichology and cosmetology, the task of preserving the structural integrity of keratin fibers under exposure to aggressive chemical factors is acquiring a fundamentally critical character. In the present work, a comparative analysis was carried out of the effectiveness of classical plex systems and an innovative proprietary technology of amino acid–lipid protection. The methodological basis of the study consisted in the use of a combination of biomimetic peptides and low-molecular-weight lipids aimed at compensating for the deficit of 18-methyleicosanoic acid (18-MEA). The results obtained in the course of the analysis indicate that the integrative approach not only maintains tensile strength at the level of leading bond-building systems but also significantly surpasses them in terms of the restoration of elasticity and hydrophobicity, as well as improvements in the sensory characteristics of the hair fiber.
