Oleic Acid – What Is It and How Does It Cause Dandruff?

SHARE

Youll find it in everything from avocados to olive oil, and it also causes dandruff. Find out what oleic acid is and how it causes dandruff.

Dandruff is caused when three things come together:

  • Malassezia globosa- A naturally occurring microbe on the scalp
  • Sebum -the natural scalp oils your scalp produces
  • Oleic acid -the byproduct created when malassezia breaks down sebum

Oleic acid forms in the last step in the process and is the thing that triggers the irritation, flakes, itching and dryness we associate with dandruff.
