Influence of thermal and chemical damage on hair: molecular restoration using amino acids and other repair agents

The article examines the impact of thermal and chemical damage on hair structure and evaluates the effectiveness of molecular restoration using amino acids and peptides. The study involved 25 participants divided into groups based on the type of hair damage. Analysis of hair structure before and after restorative procedures revealed significant improvements in strength, elasticity, and moisture retention. The application of amino acid complexes, including glycine, arginine, and cysteine, contributed to the restoration of disulfide bonds and reinforcement of keratin fibers. The results confirm the efficacy of molecular restoration and provide new insights into the mechanisms of hair structure regeneration. The scientific contribution of the work lies in the development of recommendations for personalized hair restoration methods.
