HAIR COLORING IS MY DNA HAIR STRUCTURE IN COLOR FORMULATION

The structure of hair plays a vital role in color formation, influencing how color is absorbed, retained, and ultimately appears. Hair is composed of three main layers: the cuticle, the cortex, and the medulla. Each layer contributes differently to the color process.https://affinityhairacademy.com/wp-admin/post.php?vc_action=vc_inline&post_id=4028&post_type=post

The outermost layer, the cuticle, consists of overlapping scales that protect the inner structure of the hair. In hair coloring, the cuticle must be lifted to allow color molecules to penetrate the hair shaft. This process is achieved through the use of alkaline agents, such as ammonia or other color-opening chemicals. The degree to which the cuticle is lifted affects the depth and vibrancy of the color.

Beneath the cuticle lies the cortex, the thickest and most significant layer in color formation. The cortex contains natural pigments known as melanin, which determines the hair’s natural color. During the coloring process, the cortex undergoes a chemical reaction that either removes natural pigment or deposits artificial color. Permanent hair color works by changing the structure of the melanin, resulting in a new shade. The size and type of color molecules deposited into the cortex determine how long the color will last and how vivid it will appear.

The innermost layer, the medulla, is present in some hair types but does not play a major role in the color process. While its exact function remains unclear, the medulla’s presence or absence does not significantly impact how color is absorbed.

By understanding the structure of hair, colorists are better able to select the right products and techniques to achieve the desired result while maintaining the health of the hair. Ensuring that the cuticle is gently lifted and the cortex is treated carefully allows for optimal color formation, producing long-lasting, beautiful results while protecting the hair’s integrity.
