There are many structures that make up the hair follicle. Anatomically, the triad of hair follicle, sebaceous gland and arrector pili muscle make up the pilosebaceous unit. [1] A hair follicle consists of : The papilla is a large structure at the base of the hair follicle. [4] The papilla is made up mainly of connective tissue and a capillary ...
The inner root sheath or internal root sheath of the hair follicle is located between the outer root sheath and the hair shaft. [1] It is made of three layers: Henle's layer, Huxley's layer, and the cuticle. [2] The inner root sheaf serves to protect growing hair. [3]
The outer root sheath corresponds with the stratum mucosum (stratum germinativum and stratum spinosum) [1] of the epidermis, and resembles it in the rounded form and soft character of its cells; at the bottom of the hair follicle these cells become continuous with those of the root of the hair.

The outer root sheath or external root sheath of the hair follicle encloses the inner root sheath and hair shaft. [1] It is continuous with the basal layer of the interfollicular epidermis (skin) . See also
Tissue mass is defined at 3.3 kg (ICRP-89, ICRP110) and addresses the skin's epidermis, dermis, hair follicles, and glands. The cell data is extracted from 'The Human Cell Count and Cell Size Distribution', [ 17 ] [ 18 ] Tissue-Table tab in the Supporting Information SO1 Dataset (xlsx).
Huxley's layer is the second layer of the inner root sheath of the hair and consists of one or two layers of horny, flattened, nucleated cells. It lies between Henle's layer and the cuticle . [ 1 ]
Henle's layer is the third and the outermost layer of the inner root sheath of the hair follicle, consisting of a single layer of cubical cells with clear flattened nuclei. It is named after German physician , pathologist and anatomist Friedrich Gustav Jakob Henle .
