Most people have experienced the occasional flake on their shoulders and immediately assume it’s dandruff. While dandruff is common and usually harmless, sometimes flakes on the scalp—or even on eyebrows and other body areas—may indicate a more serious skin condition that requires attention. Understanding the difference can help you address the problem effectively and maintain healthy skin.
Common Causes of Flaky Scalp
-
Dandruff (Seborrheic Dermatitis)
-
The most familiar cause of flaking.
-
Caused by oily skin, yeast overgrowth, or sensitivity to certain products.
-
Symptoms include: white or yellow flakes, itchy scalp, and mild redness.
-
Usually manageable with anti-dandruff shampoos containing zinc, ketoconazole, or selenium sulfide.
-
Dry Scalp
-
Caused by environmental factors, harsh shampoos, or low humidity.
-
Flakes are usually smaller, drier, and less oily than dandruff flakes.
-
Moisturizing shampoos and avoiding excessive heat styling can help.
