Hair Sensitization
Meaning ❉ Hair sensitization defines the acquired state of increased vulnerability and reactivity of hair and scalp due to repetitive exposure to damaging factors.
Meaning ❉ Hair Fiber Fragility refers to the inherent susceptibility of textured hair, particularly coily, kinky, and curly strands common in Black and mixed-race hair, to physical damage and breakage. This vulnerability stems from the hair shaft’s unique helical shape and numerous twists, which create points of weakness where the cuticle layers are lifted or less uniformly sealed. Understanding this characteristic is foundational for true textured hair growth, as it shifts focus from simply growing hair to retaining length by minimizing breakage. For systematized care, recognizing fragility guides the automation-like principles in routines; it means prioritizing gentle detangling methods, utilizing specific emollients and humectants to maintain elasticity, and carefully selecting tools that respect the fiber’s delicate nature. Practical application involves implementing low-manipulation styling choices, protecting ends, and adjusting wash day protocols to reduce mechanical stress. This informed approach helps maintain the integrity of each strand, allowing for consistent length retention and the healthy appearance of one’s heritage hair.
