Which glands empties sebaceous oil onto the hair? Sebaceous gland ducts thus usually open up into the upper part of a hair follicle, called the infundibulum. The infundibulum is part of the pilosebaceous canal, the one responsible for discharging sebum and one that is composed of the infundibulum and the short duct of the sebaceous gland itself.
Where does the sebaceous gland empties? Sebaceous glands are located in the mid-dermis and almost always develop alongside a hair follicle, with an outlet emptying into the follicular canal. This association is known as the pilosebaceous unit.
