Papilla – Located at the very bottom of the hair follicle, the papilla is made up of connective tissue and blood vessels that nourish the hair follicle.. Germinal Matrix – The germinal matrix is where stem cells divide to produce new hairs.. However, we’re going to look at the three main “structures” of the bulb. Essentially, DHT builds up within the hair follicle (mainly, the dermal papilla cells). In addition, there were also 10 control patients. If the papilla is damage there will be hair loss and nothing you do can change that. In addition, proper circulation is important for the delivery of oxygen.
