Meaning ❉ Lye soap making, a foundational chemical process known as saponification, transforms fats or oils with a strong alkaline solution into cleansing agents. For textured hair understanding, this process illuminates the historical reliance on rudimentary yet potent cleansing methods, often predating modern formulations. Grasping the chemistry of high alkalinity inherent in traditional lye soaps offers vital insight for systematizing a care routine, particularly when addressing product buildup or preparing strands for deep conditioning. It informs the discerning selection of clarifying treatments, recognizing the potential for cuticle elevation and moisture depletion if not followed by an acidic rinse. Practically, while direct application of highly alkaline homemade lye soap is generally not recommended for the delicate cuticle of Black or mixed hair, the knowledge empowers individuals to assess commercial product ingredients and their pH balance. It provides a foundational understanding of how different cleansers interact with the hair’s structure, guiding the implementation of routines that prioritize cuticle integrity and moisture retention, ensuring every strand receives mindful attention.
