Which two layers of hair are most affected by chemical texture services?

The cortex and cuticle are the two layers of hair that are most affected by chemical texture services. The cortex is the middle layer of the hair shaft and is crucial for determining the hair's strength, elasticity, and texture. It contains keratin and the pigment that gives hair its color. Chemical texture services, such as perms or relaxers, work primarily on the cortex to alter the hair's shape and texture. These treatments change the internal structure of the hair, allowing for the desired results.

The cuticle is the outermost layer of the hair and serves as a protective barrier. While the cuticle itself is not the primary target of chemical services, its condition can influence how the hair absorbs the chemicals used in these treatments. If the cuticle is damaged or porous, it may allow more solution to penetrate, potentially affecting the results. Proper treatment of the cuticle can also enhance the maintenance of the hair after undergoing chemical services.

Understanding the role of these layers is essential in achieving the desired effects from chemical texture services while also maintaining the health of the hair.
