GENERAL HISTOLOGY

Detailed explanation-1: -The dermal papilla contains capillaries. The papilla interacts with the matrix, which has the highest mitotic rate of any organ. The matrix is the part of the hair follicle where matrix keratinocytes proliferate to form the hair shaft of growing hair.

Detailed explanation-2: -Structure of Hair Follicle. The portion of a hair above the skin is called the shaft, and all that beneath the surface is the root. The root penetrates deeply into the dermis or hypodermis and ends with a dilation called the hair bulb.

Detailed explanation-3: -Telogen (shedding): This is the resting stage of your hair growth cycle. The hair follicle is inactive, and there’s a white bulb of keratin at the root (club hair). The bulb of keratin keeps the hair in the follicle until it sheds, which then starts the hair growth cycle over again.

Detailed explanation-4: -At the base of the hair, the hair root widens to a round hair bulb. The hair papilla, which supplies the hair root with blood, is found inside the bottom of the hair bulb. New hair cells are constantly being made in the hair bulb, close to the papilla.
