Dandruff is a common scalp condition that causes the skin to flake. It is often caused by a fungus that feeds on the scalp’s natural oils. Dandruff can be embarrassing and itchy, but it is not typically a serious medical condition.
Bald people are often less likely to get dandruff than people with hair. This is because the fungus that causes dandruff needs hair to survive. However, it is still possible for bald people to get dandruff.
