The cuticle is the outermost layer of the hair shaft, playing a critical role in protecting the hair’s internal structure. It is composed of overlapping, scale-like cells that lie flat, similar to shingles on a roof. These cells serve as a barrier against external factors such as heat, chemicals, and environmental damage, ensuring the hair’s overall health and appearance.

In the process of hair coloring or chemical treatments, the cuticle must be temporarily lifted to allow products to penetrate the deeper layers of the hair, particularly the cortex where natural pigments and hair structure reside. Alkaline agents, such as ammonia, are often used to raise the cuticle scales and open up the hair shaft, enabling color molecules or other chemicals to be absorbed. The degree to which the cuticle is opened impacts the intensity and longevity of the color treatment.

Healthy cuticles lie flat and smooth, reflecting light and giving hair its natural shine and softness. When the cuticle is damaged or raised—due to excessive heat styling, harsh chemical treatments, or environmental stressors—hair can become rough, dull, and prone to tangling and breakage. Over time, a damaged cuticle can lead to issues such as dryness, split ends, and reduced elasticity, making hair more vulnerable to further damage.

Proper care and maintenance of the cuticle are essential for maintaining healthy hair. Conditioning treatments, moisturizing shampoos, and heat protectants help keep the cuticle smooth and intact, ensuring the hair remains shiny, soft, and manageable. Avoiding excessive heat and chemical exposure also contributes to preserving the cuticle’s integrity. By protecting the cuticle, overall hair health is improved, allowing for better results from coloring, styling, and other treatments.https://en.wikipedia.org/wiki/Cuticle_(hair)hair coloring is my DNA
