How Does Bleaching Affect the Hair Structure?

Bleaching affects the hair structure by altering its composition. The process involves using chemical agents, primarily hydrogen peroxide and ammonia, to strip the natural pigment from the hair. This chemical reaction raises the hair cuticles, which are the outer protective layer. When cuticles lift, moisture escapes, leading to dryness and brittleness.

Bleaching weakens the protein structure of hair, known as keratin. The disruption of keratin results in increased porosity, making hair more prone to damage. Over time, this damage can manifest as split ends and breakage. Additionally, bleached hair can lose its elasticity, resulting in a lack of bounce and shine.

In summary, bleaching affects hair by altering its chemical structure, increasing porosity, and leading to dryness and damage. These changes significantly affect hair health and appearance.

What Changes Will You See in Your Hair Color?

The changes you will see in your hair color can vary depending on several factors, including your natural color, the method used, and your hair’s condition.
