Hair

This complex interaction induces the hair follicle to produce different types of hair as seen on different parts of the body.
Hair is a protein filament that grows from follicles found in the dermis.

Skin

cutaneousskin cellanimal skin
It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions.
It also contains the hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels.

Arrector pili muscle

arrector piliarrector pilliarrectores pilorum
Other structures associated with the hair follicle include the cup in which the follicle grows known as the infundibulum, the arrector pili muscles, the sebaceous glands, and the apocrine sweat glands.
The arrector pili muscles are small muscles attached to hair follicles in mammals.

Hirsutism

increased hair growthhirsuteexcessive hair growth
Well known diseases of the hair follicle include alopecia or hair loss, hirsutism or excess hair growth and lupus erythematosus.
Hirsutism can be caused by either an increased level of androgens, the male hormones, or an oversensitivity of hair follicles to androgens.

Human hair growth

catagenhair growthgrowth
The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides and immune cells.
Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen.

Goose bumps

piloerectiongoose pimplesgooseflesh
This process results in goose bumps (or goose flesh).
Goose feathers grow from spores in the epidermis which resemble human hair follicles.

Sebaceous gland

sebumsebaceous glandssebaceous
Other structures associated with the hair follicle include the cup in which the follicle grows known as the infundibulum, the arrector pili muscles, the sebaceous glands, and the apocrine sweat glands. Anatomically, the triad of hair follicle, sebaceous gland and arrector pili muscle make up the pilosebaceous unit.
There are two types of sebaceous gland, those connected to hair follicles, and those that exist independently.

Hair loss

Well known diseases of the hair follicle include alopecia or hair loss, hirsutism or excess hair growth and lupus erythematosus.
Hair follicle growth occurs in cycles.

Sweat gland

sweat glandsporesweat
Other structures associated with the hair follicle include the cup in which the follicle grows known as the infundibulum, the arrector pili muscles, the sebaceous glands, and the apocrine sweat glands.
Rather than opening directly onto the surface of the skin, apocrine glands secrete sweat into the pilary canal of the hair follicle.

Hair plexus

hair follicle receptors
Hair follicle receptors sense the position of the hair.
Each hair plexus forms a network around a hair follicle and is a receptor, which means it sends and receives nerve impulses to and from the brain when the hair moves.

Dermis

dermaldermal papillaepapillary dermis
It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions.
In addition, hair follicles, sweat glands, sebaceous glands (oil glands), apocrine glands, lymphatic vessels, nerves and blood vessels are present in the dermis.

Telogen effluvium

hair loss
This condition is called telogen effluvium.
Telogen effluvium is a scalp disorder characterized by the thinning or shedding of hair resulting from the early entry of hair in the telogen phase (the resting phase of the hair follicle).

Hair transplantation

hair transplanthair transplant surgeryhair transplants
Hair follicles form the basis of the two primary methods of hair transplantation in hair restoration, Follicular Unit Transplantation (FUT) and follicular unit extraction (FUE).
Hair transplantation is a surgical technique that removes hair follicles from one part of the body, called the 'donor site', to a bald or balding part of the body known as the 'recipient site'.

Dihydrotestosterone

5α-DihydrotestosteroneDHT17-hydroxyandrostan-3-one
These follicles are extracted from donor areas of the scalp, or other parts of the body, which are typically resistant to the miniaturization effects of the hormone DHT.
The enzyme 5α-reductase catalyzes the formation of DHT from testosterone in certain tissues including the prostate gland, seminal vesicles, epididymides, skin, hair follicles, liver, and brain.

Follicular unit extraction

FUE
Hair follicles form the basis of the two primary methods of hair transplantation in hair restoration, Follicular Unit Transplantation (FUT) and follicular unit extraction (FUE).
Follicular unit extraction (FUE), also known as follicular transfer (FT), is one of two primary methods of obtaining hair follicles, naturally occurring groups of one to four hairs, for hair transplantation.

Management of hair loss

hair restorationBaldness treatmentsExercise and Hair Loss
Hair follicles form the basis of the two primary methods of hair transplantation in hair restoration, Follicular Unit Transplantation (FUT) and follicular unit extraction (FUE).
Hair transplantation is a surgical technique that moves individual hair follicles from a part of the body called the donor site to bald or balding part of the body known as the recipient site.

Follicular unit transplantation

follicular unit
Hair follicles form the basis of the two primary methods of hair transplantation in hair restoration, Follicular Unit Transplantation (FUT) and follicular unit extraction (FUE).
Follicular unit transplantation (FUT) is a hair restoration technique, also known as the strip procedure, where a patient's hair is transplanted in naturally occurring groups of 1 to 4 hairs, called follicular units.

Pattern hair loss

androgenic alopeciamale pattern baldnessscalp hair loss
It is this miniaturization of the hair shaft that is the primary predictive indicator of androgenetic alopecia, commonly referred to as male pattern baldness or male hair loss.
Types 1 and 2 5α reductase enzymes are present at pilosebaceous units in papillae of individual hair follicles.
