What layer is the main part of the hair shaft?
The main part of the hair shaft is located in the cortex layer. This layer is composed of keratin and contains the pigment that gives hair its color. The cortex also determines the strength, elasticity, and texture of the hair.
Where in the hair are pigment granules found?
Pigment granules, which determine hair color, are found in the cortex layer of the hair shaft. They are produced by cells called melanocytes and are responsible for producing melanin, which gives hair its color.
Why does your hair gray when you get older?
Each hair follicle contains a certain number of pigment cells. As we age the pigment cells in the hair follicles gradually die and the hair turns gray, silver, or white.
What is the layer of epidermis that has pigment-producing melanocytes?
The layer of the epidermis that has pigment-producing melanocytes is the stratum basale (basal layer). Melanocytes produce melanin, the pigment responsible for skin color, and transfer it to surrounding keratinocytes.
Does darker hair contain more oils than lighter hair?

The cuticle is the outer scale section of the hair. it contains 10% of the hair"s weight. A healthy cuticle will result in a shine, glossy. smooth and soft textured hair. The cortex is the inner section of the hair shaft. This contains for 75% of the hair's strength. In the cortex is where the chemical bonds are broken. The medulla this is in the innermost part of the hair. It consist of tunnels of cells filled with air spaces running continuously or intermittently through the hair.
