Hair is composed of 3 Principle Layers

The Medulla

  • Composed of round cells 2 or 5 rows across
  • Sometimes called the pith or marrow of the hair
  • Thick or coarse hair usually contains a Medulla
  • Fine and naturally blonde hair generally lacks a Medulla
  • The purpose of the Medulla has not been determined

The Cortex

  • Composed of a fibrous protein core
  • The cells are elongated and tightly bound together
  • Contains Melanin pigment which is responsible for
  • Strength, Elasticity and Tenacity
  • Chemical changes take place in the Cortex when
  • Colouring, Perming, Relaxing or Straightening

The Cuticle

  • The outermost layer of the hair
  • Composed of scale like single layer cells
  • The cuticle protect the Cortex and Medulla
  • Products with a High PH cause the cuticle layer to swell allowing liquids into the Cortex
  • Products with a Low PH cause the cuticle to shrink and harden
