Meaning ❉ Cohesion Biology refers to the biological mechanisms by which individual elements unite, forming a stable, functional unit. Within the context of textured hair, this concept clarifies the forces maintaining each strand’s structural integrity. It speaks to the precise adherence of cuticle layers and the steadfastness of internal keratin bonds, especially vital for Black and mixed-race hair. Given the inherent architecture of curls and coils, which can present unique points of tension, comprehending these cohesive forces becomes foundational for hair preservation. Applying this knowledge within a systematized hair care approach involves selecting formulations that gently reinforce the hair’s natural framework. Such a methodical approach, much like an automated sequence, ensures consistent reinforcement of the hair’s intrinsic resilience. Practical implementation of this understanding guides the deliberate selection of humectants, emollients, and conditioning agents. These choices support optimal strand health, promoting length retention and minimizing mechanical stress.
