How Does Hair Bleaching Alter the Natural Hair Structure?

Hair bleaching alters the natural hair structure by using chemicals to remove pigment. The primary component of many bleaching products is hydrogen peroxide. This chemical penetrates the hair shaft and oxidizes the natural color pigments, leading to a lighter shade.

As the bleaching process occurs, it disrupts the protein structure in the hair. Specifically, it breaks down keratin, the protein that makes up most of the hair’s strength and texture. This breakdown can lead to a range of physical changes. These changes include increased porosity, leading to a drier and more fragile hair texture.

Additionally, the cuticle, which is the outermost layer of the hair, can become damaged or lifted. This damage exposes the inner layers of the hair, making it more susceptible to environmental factors and further damage.

In summary, hair bleaching alters the natural structure by removing color, weakening proteins, and damaging the cuticle, resulting in changes in texture, strength, and moisture retention.

How Can You Spot Over-Processed and Brittle Hair?

You can spot over-processed and brittle hair by observing its texture, appearance, and response to styling. Key indicators include dryness, breakage, split ends, and a lack of elasticity.

Texture: Over-processed hair often feels dry and rough. It lacks moisture because chemical treatments strip away natural oils. A study by a team of researchers in the Journal of Cosmetic Science (Smith et al., 2021) indicates that hair loses up to 50% of its moisture after chemical treatments.
Appearance: Brittle hair appears dull and lifeless. The shine typically seen in healthy hair diminishes significantly. The loss of cuticular layers during processing results in light refraction issues, causing a lack of shine.
Breakage: Brittle hair breaks easily when subjected to tension during styling or brushing. According to a study published in the International Journal of Trichology (Kumar, 2020), individuals with over-processed hair can experience a 70% increase in breakage compared to those with untreated hair.
Split Ends: Over-processed hair is more prone to split ends and fraying. The ends may fray and look uneven. The structural integrity decreases due to the weakening of keratin, the protein that constitutes hair strands.
Lack of Elasticity: Healthy hair stretches slightly but returns to its original form. Brittle hair loses this elasticity, making it prone to snapping instead of bending. A study in the Hair Care Journal (Jones, 2019) found that hair treated excessively with chemicals could lose elasticity by more than 40%.

These characteristics combined indicate that hair is over-processed and in a brittle state, often requiring significant care or restorative treatments.
