Hair characteristics->
follicle->
hair is an appendage of the skin that grows. The follicle contains more than enough cells for simple "DNA" analysis.
Root->
The length of a hair extends from the root embedded in the follicle. A single root contains sufficient "DNA" for analysis.
Cuticle->
The cuticle is the outside covering of the hair. It is formed by overlapping scales that always point toward the tip of the hair. Those scales are hardened and flattened while progressing from the follicle.
Cortex->
The interior of the hair. Embedded with pigment granules that impart color to hair. Composed of spindle-shaped cortical cells alined in a regular array, parallel to the length of the hair.
Medulla->
A collection of cells appears as a canal running through the center of the hair. The medulla is the most predominant hair feature in many species.
Medulla index->
The percentage or fraction of the hair's width occupied by the medulla [between 0 and 1].
