Scalp vs. Hair

Scalp vs. Hair

Distinguishing between the scalp and hair is crucial, as catering to their individual needs forms a significant aspect of comprehending product effectiveness.

SCALP includes 5 layers.

  • S: The skin. Where the hair grows and the home of the follicles
  • C: Connective tissue. Layer of fat and tissue containing the nerves and blood vessels 
  • A: The aponeurosis called epicranial aponeurosis of dense tissue and muscle 
  • L: The loose areloar connective tissue that  provides an easy plane of separation between the upper three layers and the pericranium
  • P: The pericranium area of the skull bones and provides nutrition to the bone and the capacity for repair

NAJEAU'S focus is on the SCALP. By feeding the skin (oils) and stimulating the connective tissue (the massaging) hair is encouraged to grow stronger and the hair follicle receives optimum nutrition. 


HAIR is a protein filament that grows out of the follicle and is divided in two parts:

  • The hair follicle, or, when pulled from the skin, the bulb or root. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair after it falls out, but also are recruited to regrow skin after a wound.
  •  The hair shaft, which is the hard filamentous part that extends the skin surface.

Conditioners and hair serums should be used and should mainly focus on the hair and hair shaft leaving the scalp open and clean to breathe and remain unclogged.


Rule of thumb:  If you wouldn’t use it on your face, would you use it on your SCALP?
