1. Introduction
Hair and scalp are essential components of human anatomy, playing significant roles in personal appearance, self-esteem, and overall health. Understanding their properties is crucial for maintaining healthy hair and scalp.
Hair, a fibrous protein known as keratin, emerges from the scalp, which is a specialized region of the skin covering the skull. Various types of hair and scalp conditions exist, each with unique characteristics and implications.
2. Hair Structure: Properties Of The Hair And Scalp Chapter 11
Hair comprises three primary layers: the cuticle, cortex, and medulla.
The cuticle, the outermost layer, consists of overlapping scales that protect the inner hair shaft from damage. The cortex, the middle layer, provides strength and elasticity to the hair. The medulla, the innermost layer, is responsible for hair insulation and color.
Hair proteins, including keratin, trichohyalin, and filaggrin, determine hair’s strength, texture, and color.
3. Scalp Structure
The scalp consists of three layers: the epidermis, dermis, and hypodermis.
The epidermis, the outermost layer, contains cells that produce keratin and melanin, the pigment responsible for hair color. The dermis, the middle layer, contains blood vessels, nerves, and hair follicles. The hypodermis, the innermost layer, provides insulation and support to the scalp.
Scalp cells, including keratinocytes, melanocytes, and sebaceous glands, contribute to hair growth, pigmentation, and scalp health.
