Function of connective tissue papilla?
Connective tissue papilla is a vascular process or form of connective tissue extending into and nourishing the root of a hair, feather, or developing tooth. Many skin papilla extend from the dermal layer into the epidermal layer.
Does minoxidil cause dark circles?
yeah man..... Inhibitory effects of bFGF, VEGF and minoxidil on collagen synthesis by cultured hair dermal papilla cells.
Can drugs stop hair growth?
Medications for hair loss treatment prevent the conversion of testosterone to dihydrotestosterone (DHT) in the body.Dihydrotestosterone is a sex steroid and androgen hormone that plays a major role in hair loss. Male pattern baldness is caused by the hair follicle's sensitivity to DHT. The follicles shrink, resulting in a shorter lifespan and the abnormal production of hair. The most important part of the hair follicle is the dermal papilla which is responsible for the growth of hair. The dermal papilla cells divide and differentiate to form new hair follicles. The papilla is in direct contact with the skin's blood capillaries, from which it gets its essential nutrients for proper hair follicle growth. The dermal papilla has a large number of androgen receptors (more in males than females). When DHT gets to the dermal papilla, it undermines the absorption of vital nutrients required for healthy hair follicles. Hair follicles have resting and growing phases - without proper nutrition, their resting stages get longer while their growing phases get shorter.

What is the name given to the pocket of epidermal and dermal cells that the hair grows within?
That would be the follicle. The hair follicle is a small tubular cavity containing the root of a hair; small muscles and sebaceous glands are associated with hair follicles.A mature hair follicle contains a bulb holding the dermal papilla cells, a hair shaft extending from the bulb through to the outer exterior of the epidermis, and a dermal sheath which provides an external covering of tissue around the bulb and along the length of the follicle.The hair follicle extends through the dermis, a hypodermis (a loose layer of connective tissue below the dermis), and a fat (or adipose) layer. In adults, molecular signals between the dermal papilla and the epidermal component of a follicle cause the hair to enter an active growth phase from an inactive phase.
What function of fungiform papilla?

What is the follicle of the hair?
The hair bulb is the lowest area or part of the hair strand. It's the thickened, club-shaped structure that forms the lower part of the hair root. The lower part of the hair bulb fits over & covers the dermal papilla.
