Meaning ❉ The medulla is the innermost, often discontinuous, core of the hair strand, a central canal frequently observed in the robust, thicker hair types characteristic of Black and mixed-race heritage. Grasping its presence provides a fundamental key to understanding how your unique textured hair interacts with its environment and products. For textured hair comprehension, recognizing the medulla’s influence informs insights into hair’s intrinsic strength and its capacity for hydro-absorption. This awareness steers the systematization of your care routine, allowing for the precise calibration of products and techniques, much like programming an efficient system for consistent results. Practical application of this knowledge means acknowledging that hair with a distinct medulla may benefit from particular strategies for hydration and thermoprotection, ensuring optimal product uptake and preserving structural soundness during styling. This gentle wisdom supports personalized care, honoring the distinct characteristics of your ancestral strands.
