Meaning ❉ Nightly Hair Hydration designates the thoughtful, consistent application of moisture to textured hair before periods of rest. This practice addresses the inherent architectural needs of Afro-descendant and mixed-heritage strands, where natural sebum distribution can be slower along the coil, leading to dryness. A systematic approach, it acts as a gentle, proactive measure within a routine, aiming to maintain the hair’s internal water balance. Regular attention during slumber aids in preserving cuticular integrity, thereby lessening friction damage and helping to retain length. Practical application often involves a water-based leave-in or light botanical oil, sealed with a satin bonnet or pillowcase, allowing the hair to remain supple and protected through the night. This methodical commitment contributes to the sustained vitality of coils and curls, fostering a healthier hair environment over time.
