Hair 101: What is Hair Made of?

Cortex
  • Spindle-shaped cells aligned along the fiber containing the fibrous proteins
  • Natural pigment (Melanin) resides deep in here
Cuticle
  • Layers of flat overlapping scale-like structures
  • Designed to prevent penetration
Medula
  • Located near the center of the fiber

 
(Dyes or Bleaches must penetrate the cuticle and travel through to the cortex)
