Sebum distribution describes the delicate descent of the scalp’s intrinsic oils along the hair shaft, a process fundamentally shaped by the unique helical architecture of textured hair. For coils and curls, this natural pathway presents distinct challenges; the winding structure often impedes the smooth travel of protective lipids, leading to varying levels of moisture across the strand. A deep understanding of this inherent characteristic forms the bedrock for systematizing hair care, allowing for an intentional allocation of hydration and nourishment precisely where the hair needs it most, from scalp to tip. This nuanced insight facilitates the practical application of bespoke routines, ensuring each individual strand receives its vital lipid coating, thus supporting the overall health and resilience intrinsic to Black and mixed-race hair. Applying this knowledge enables the creation of an optimized environment, supporting consistent care and sustained vibrancy.
