To understand how bleach attacks hair, one must first understand what hair is. Human hair is primarily composed of keratin, a tough, fibrous protein held together by disulfide bonds. These bonds are the molecular “rungs” of a ladder, giving hair its strength, elasticity, and shape. Pigment, or melanin, resides within the cortex of the hair, providing its natural color. Bleach, typically a mixture of hydrogen peroxide and an alkalizing agent like ammonia, is designed to lighten hair by oxidizing the melanin. This reaction neutralizes the color molecules, turning them colorless. However, the oxidizing agents are not selective; they are chemical bullies that attack anything in their path, including the disulfide bonds of the keratin.
Hair is slightly acidic, while bleach is highly basic. When they interact, the bleach initiates a chemical reaction that breaks the hair fibers down into a fluid-like salt and water mixture. will bleach dissolve hair
Yes, liquid household bleach (sodium hypochlorite) can dissolve hair, though it is primarily effective for clearing clogs in bathroom drains. Because bleach is highly basic, it chemically attacks the acidic proteins (keratin) in hair, breaking them down into a liquid state over time. To understand how bleach attacks hair, one must
Dissolving a typical "clog-sized" wad of hair usually takes between 30 and 90 minutes . Why Bleach Often Fails as a Drain Opener Pigment, or melanin, resides within the cortex of
