Most people don’t realize that a flaky scalp — or dandruff — can be a very mild form of seborrheic dermatitis. The main difference between the two conditions is that dandruff has milder symptoms and is limited to the scalp, while seborrheic dermatitis can develop in other areas of the body and cause more symptoms due to inflammation.

• Seborrheic dermatitis and dandruff might seem similar because they both lead to an itchy, flaky scalp, but they are not identical conditions.


• Seborrheic dermatitis is a more serious and long-lasting skin condition that can affect other parts of the body, not just the scalp.


• Seborrheic dermatitis symptoms usually affect the scalp but can develop anywhere on the body that has oil-producing glands. Although dandruff can be a symptom, it also causes discolored scales, rash, and itchiness.
