What part of the hair projects above the epidermis?

Explanation:
The part of the hair that projects above the epidermis is the hair shaft. It is the keratinized, dead portion of the hair that extends from the hair root, through the follicle, and out to the skin surface. The root stays below the surface inside the follicle, anchored by the bulb and nourished by the papilla. The bulge is a region within the follicle that houses stem cells, not the visible portion. The hair papilla provides nutrients at the base of the follicle, and intermediate hair or vellus hair refers to hair types, not the part that sticks out. So the visible, above-skin portion is the hair shaft.
