1.6.2 Introduction to Hair and Trichology

Hair is a remarkable ornament, distinguished by its varying colors, textures, and styles. It serves as a unique form of personal expression, reflecting individual identities and aesthetics throughout human history. The comprehensive scientific exploration of hair, including its structure and the myriad conditions and issues it can experience, is known as "Trichology." This term is derived from the Greek words "Trichos" (meaning hair) and "Ology" (indicating the study of). Trichology encompasses the study and practice of understanding everything about hair, from its composition to its diverse states and challenges.

1.6.4 The Structure of Hair

The integument, comprising hair, skin, and nails, constitutes the body's outer covering and its largest and fastest-growing organs. Fully grown human hair is divided into two parts: the hair root and the hair shaft.

A. The Hair Root

This portion of the hair is located beneath the scalp's surface and consists of several key structures, including the follicle, hair bulb, papilla, arrector pili muscle, sebaceous glands, and sudoriferous glands.

1. Follicle: The hair follicle serves as the base for each hair strand and is situated beneath the skin. Hair growth commences within the follicle, where new hair cells are generated. Follicles are distributed across the body, with the exception of areas like the palms, soles, lips, and eyelids. It's not uncommon for multiple hairs to grow from a single follicle.

2. Hair Bulb: The lowermost portion of the hair strand is called the hair bulb, distinguished by its thickened, club-shaped structure.

3. Dermal Papilla: Located at the base of the hair bulb, the dermal papilla contains blood vessels that supply vital nutrients and oxygen necessary for hair growth.

4. Arrector Pili Muscles: Each hair follicle is connected to tiny arrector pili muscles. These muscles contract in response to fear or cold, causing the hair to stand on end, leading to the formation of "goosebumps."

5. Sebaceous Glands: Often associated with hair follicles, sebaceous glands produce sebum, an oily substance that serves to lubricate and prevent hair from drying out.

6. Sudoriferous Glands: Also referred to as sweat glands, sudoriferous glands play a vital role in regulating body temperature by producing sweat. There are two primary types of sweat glands: eccrine and apocrine sweat glands.

7. Eccrine sweat glands are distributed almost all over the human body, in varying densities. Its water-based secretion represents a primary form of cooling in humans.

8. Apocrine sweat glands are mostly limited to the axilla (armpits) in humans.
