Dandruff, or seborrheic dermatitis, affects millions of Americans each year. It is common in neonates, called “cradle cap”, and then clears on its own and increases into adulthood, however can occur at any age. Contrary to popular belief that seborrheic dermatitis can only occur on the scalp, it is quite common on the eyebrows, nasal creases, beard, armpits, ears, chest, back, and genitals.


  • White scales in the scalp that can fall onto shoulders
  • Scalp itch
  • Redness or inflammation on the scalp
  • Increase in oil production

Dandruff is thought to be caused by a sensitivity and reaction to a naturally occurring yeast on the scalp, Malassezia, and genetic predisposition. Though it is common and can be quite severe in healthy individuals, it is also worse in some disorders such as Parkinson’s Disease and HIV infection. There are also many conditions that can mimic dandruff, such as ringworm and psoriasis, so it is important to see a board-certified dermatologist if you the dandruff is not under control.
