Meaning ❉ Sebum distribution refers to the natural spread of the scalp’s protective lipids along each hair strand. For textured hair, particularly the tightly coiled and zig-zag patterns common among Black and mixed-race individuals, this natural process presents a distinct consideration. The very architecture of these strands, with their numerous bends and curves, naturally impedes the even descent of sebum from the scalp’s epidermal layer down to the lengths and delicate ends. This often leads to a discernible disparity: a scalp that may feel quite oily, juxtaposed with lengths and ends that remain thirsty and more susceptible to environmental stressors or mechanical strain. Recognizing this fundamental aspect of textured hair growth allows for a systematic approach to care, moving beyond general advice to precision. It guides the thoughtful placement of emollients and hydrators, ensuring each curl and coil receives its necessary protective coating, rather than relying solely on the scalp’s limited reach. The practical application of this understanding involves tailoring routines with intention, perhaps through targeted oiling for dry segments, gentle cleansing to preserve the scalp’s delicate lipid barrier, and styling choices that support moisture retention, ultimately supporting the hair’s intrinsic resilience and appearance.
