HAIR COLORING IS MY DNA Â 0aac0e2893294f148fb879ac871ae4a8 
The structure of human hair is composed of several layers and elements that give it its unique shape, strength, and texture. Hair is primarily made of keratin, a fibrous protein that gives it strength and flexibility. It is divided into three main parts: the cuticle, the cortex, and the medulla.
The cuticle is the outer layer and acts as a protective barrier. This layer is made up of tiny, overlapping, scale-like cells, helping to protect the hair from external damage, such as pollution and heat. A healthy cuticle typically makes hair shiny and manageable. However, when this layer is damaged, it can become dull and brittle.
The cortex, located beneath the cuticle, is the thickest part and represents the core of the hair. The cortex contains the keratin fibers that give hair its strength and elasticity. This layer also contains the melanin pigments that determine hair’s natural color.
The medulla is the central layer and is found only in some hair types. Its function is not fully understood, and it is often considered to contribute little to the hair’s overall structure and strength.
It’s important to keep in mind that hair health depends largely on the integrity of these three layers. When hair is exposed to harsh chemicals, excessive heat, or lack of hydration, the cuticle can deteriorate, affecting the cortex and, consequently, the hair’s strength and appearance. Therefore, it’s essential to care for it with appropriate products and minimize damage to maintain its healthy structure and optimal appearance. READ MORE
