Keratin Degradation

Meaning ❉ Keratin degradation gently describes the structural weakening of the hair’s primary protein, keratin, leading to diminished strand integrity. This process, often unseen until breakage becomes apparent, manifests as a compromise to the hair’s natural resilience and curl pattern, particularly vital for the intricate formations of coils, curls, and waves. Factors such as diligent manipulation during styling, environmental exposures, or the repeated application of heat and chemical agents can gradually erode the protein bonds that lend strength and elasticity to textured hair. Understanding this molecular shift guides the discerning individual toward a systematized approach to hair well-being, fostering routines that prioritize gentle handling and protective practices. Thoughtful product selection, including those that support the hair’s protein structure or offer a delicate moisture shield, becomes paramount. This awareness permits a deliberate tending to hair health, preserving the vibrant vitality and characteristic spring unique to heritage strands.
