PHYSICAL WELLNESS

your body’s protective layer

HAIR

Hair might seem simple, but it serves important roles in protection, temperature regulation, and even communication. Think of it like natural clothing fibers—soft, lightweight, and designed specifically for your body. Just like a sweater keeps you warm and helps shield your skin, hair helps insulate and protect you, while also sending sensory signals to the brain.

  • Protects scalp from UV rays and physical injury

  • Provides insulation by trapping heat close to the skin

  • Enhances sense of touch by amplifying sensations through hair follicles

  • Acts as a barrier (eyelashes, nose hairs, eyebrows) to keep dust, dirt, and bugs out

  • Plays a role in communication and self-expression

HAIR BASICS

Common Terms + Simple Definitions

Here’s a mini glossary for hair-related words you’ll see throughout the site:

  • Hair Follicle – The small pocket in the skin where each hair grows

  • Shaft – The visible part of the hair (what you see and style)

  • Root - The part of the hair below the skin, anchored in the follicle

  • Keratin – A strong protein that makes up hair, nails, and skin

  • Sebaceous Glands – Glands attached to follicles that produce oil to keep hair moisturized

  • Melanin – Pigment that gives hair its color

WHAT HAIR WORK WITH

HAIR + OTHER SYSTEMS

  • Skin → Hair grows out of the skin and works closely with sweat and oil glands

  • Nervous System → Tiny nerve endings at the base of each hair detect movement (like a bug crawling)

  • Endocrine System → Hormones influence hair growth, thickness, and texture

  • Circulatory System → Delivers nutrients and oxygen to hair follicles through the blood

HealthY HAIR…

Like skin, healthy hair depends on hydration, nutrition, and care. A balanced diet, gentle cleansing, managing stress, and avoiding harsh chemicals can help your hair grow stronger and look its best.
