UV Radiation Damage
Meaning ❉ UV radiation damage refers to the molecular and structural degradation of hair caused by sun exposure.
Meaning ❉ Hair UV Damage signifies the structural weakening of hair fibers, particularly the delicate melanin and protein bonds, stemming from prolonged exposure to the sun’s ultraviolet radiation. For textured hair, especially the unique coils and kinks common to Black and mixed-race hair, this external stress can noticeably diminish natural elasticity and moisture retention, leading to dryness, brittleness, and a muted appearance. Understanding this environmental influence serves as a foundational element in developing robust hair knowledge. In systematizing care, recognizing UV damage prompts the consistent inclusion of protective measures as a routine principle; this suggests considering sun-protective styles or products with UV filters as an automatic step, much like hydration is for textured strands. Practical application involves regularly applying leave-in conditioners containing UV protection, choosing wide-brimmed hats, or opting for protective styles when outdoors. This thoughtful approach helps maintain the integrity and vitality of our heritage hair against daily environmental challenges.
