Meaning ❉ Disulphide Bond Chemistry refers to the fundamental molecular connections within hair’s protein structure, particularly vital for the distinct contours and resilience found in textured strands. These robust chemical links, formed between sulfur atoms in cysteine amino acids, dictate the very architecture of curls, coils, and waves, influencing how hair naturally holds its shape. For those navigating the care of Black and mixed heritage hair, comprehending these bonds provides a grounded insight into why certain routines yield predictable results. It offers clarity on the underlying mechanics of processes like chemical texturizing, where these bonds are carefully manipulated to alter curl patterns, or how heat styling temporarily reconfigures them. This knowledge offers a gentle yet precise framework for systematizing hair care, moving beyond trial-and-error to a deliberate implementation of practices that honor the hair’s inherent design, promoting its enduring vitality and integrity.
