Study Notes
Hair Structure
- Hair consists of three main components: the shaft, the root, and the follicle.
- The hair shaft is the visible part that extends above the skin's surface.
- Keratin, a protein, primarily composes the hair shaft, providing strength and flexibility.
Hair Root and Follicle
- The hair root is located beneath the skin and secures the hair to the scalp.
- Hair follicles are small structures where hair grows and contains the hair bulb, responsible for the production of new hair cells.
Scalp Functions
- The scalp acts as a protective barrier against environmental threats like UV radiation and physical damage.
- Sebaceous glands in the scalp produce sebum, which is crucial for moisturizing hair and acting as a defense against dryness and bacteria.
Scalp Health and Hair Growth
- A well-moisturized scalp contributes to the prevention of dandruff and supports healthy hair growth.
- A dry scalp can result in issues like itching, flaking, and hair breakage.
- The scalp has a rich supply of blood vessels that provide necessary nutrients and oxygen to hair follicles, essential for maintaining hair health.
Importance of Hair and Scalp Health
- Maintaining the health of both hair and scalp is vital for preventing hair disorders.
- Healthy hair and scalp contribute to a vibrant appearance and enhance overall protection for the hair system.
