Hair follicle of Felidae. Every strand of hair is built up on the medulla, cortex, and cuticle.[7] The innermost area, the medulla, is really an open up and unstructured region that's not usually present.[8] The remarkably structural and arranged cortex, or 2nd of three levels of your hair, is the key source of mechanical power and drinking water uptake. The cortex includes melanin, which shades the fiber depending on the variety, distribution and kinds of melanin granules. The melanin could be evenly spaced or cluster throughout the edges with the hair.[nine] The shape in the follicle decides the shape on the cortex, and The form of the fiber is connected with how straight or curly the hair is. Individuals with straight hair have spherical hair fibers. Oval and various formed fibers are generally more wavy or curly. The cuticle is the outer Kirkland covering.
