SAFE HAIR TRANSFORMATIONS: ANALYSIS OF PERSONALIZED METHODOLOGIES FOR SENSITIZED HAIR

Abstract

This study aimed to analyze safe hair transformations, focusing on the application of customized methodologies for sensitized hair, addressing the structure and composition of the hair fiber, the impacts of chemical procedures, and the development of specific protocols. The research was conducted through a qualitative literature review, gathering scientific articles published in specialized journals, prioritizing recent and relevant studies for the field. The collected information was organized into thematic axes, allowing an understanding of the interrelationships between structural composition, damage mechanisms, and recovery strategies. The results showed that procedures such as bleaching, straightening, and oxidative coloring cause degradation of proteins, lipids, and water, as well as irreversible changes in the keratin disulfide bonds, compromising strength, elasticity, and shine. It was observed that customized protocols, based on precise diagnosis and careful selection of reconstructive, moisturizing, and nourishing actives, present superior results in functional fiber restoration, reducing risks and prolonging the durability of aesthetic results. It was also identified that the use of real-time diagnostic technologies, such as portable microscopy and conductivity measurements, enhances the safety and effectiveness of interventions. The final considerations reinforce the importance of integrating scientific knowledge, technological resources, and practices adapted to the individuality of the hair fiber as a means to ensure safe, long-lasting, and aesthetically pleasing hair transformations, preserving fiber integrity and functionality in the long term.
