Bleach Dissolve Hair | Will

This is where the process of dissolution begins. When bleach breaks a disulfide bond, it converts the amino acid cystine into cysteic acid. Each broken bond represents a loss of structural strength. As the bleaching process continues, more and more of these bonds are severed. The hair shaft, once a coiled and robust structure, begins to lose its resilience. The cuticle—the protective outer scale layer—is lifted and eroded, leaving the inner cortex exposed and porous. At this stage, wet hair feels stretchy and elastic. Pushed further, it becomes sticky and mushy, a condition stylists call “over-processed.” In this state, the hair has not turned into a liquid solution, but its protein structure has been so thoroughly oxidized and fragmented that it loses all mechanical integrity. A gentle tug will cause the hair to stretch and snap, or simply dissolve into a wet, pasty pulp. This is a functional dissolution: the organized solid of the hair shaft has been chemically reduced to a disorganized, soluble mass of protein fragments.
