Structure of Hair
- Follicle- small cavity of cells and connective tissue below the surface of the skin
- Shaft- comprised of the dead keratin cells
Cortex- largest part of the hair shaft
Outer Root Sheath “ORS”- encloses the hair fiber and inner root sheath
Inner Root Sheath “IRS”- enclosed by the outer root sheath, will never keratinize
Hair Bulb- largest part of the hair follicle, very bottom of the follicle base
Dermal Papilla- nourishes the bulb, producing new growth at a rapid rate
“Blood Vessels are also necessary to keep the hair and skin healthy”
