Meaning ❉ External Fatty Acids represent a class of lipid compounds, often derived from botanical sources, that are intentionally introduced to the hair and scalp. For textured hair, particularly Black and mixed hair types, their significance is pronounced: they function as gentle emollients and occlusives, aiding in the retention of vital moisture within the strand. This thoughtful application supports the hair’s natural pliability and reduces friction, which is paramount for maintaining strand integrity during manipulation and styling. When these beneficial lipids are systematically incorporated into a hair care routine—perhaps as a pre-shampoo treatment or a sealing agent—they contribute to a predictable outcome of softer, more manageable hair. This consistent provision helps to minimize mechanical stress, thereby supporting the appearance of length and overall hair health, making daily care feel less like a chore and more like a gentle, informed practice.
