Itchy Scalp: What Are the Possible Causes? Answers From a Dermatologist

When to See a Dermatologist

If scalp itching:

• Lasts longer than two weeks
• Is accompanied by hair loss, pain, or bleeding
• Does not improve with over-the-counter treatments

…it’s time to consult a dermatologist. A proper diagnosis ensures the right treatment—and faster relief.

The Bottom Line

An itchy scalp isn’t something you should ignore. While many causes are harmless and easy to treat, persistent itching may indicate a condition that needs medical care. With the right diagnosis and treatment plan, most people can find lasting relief.

If symptoms persist, a dermatologist can help identify the cause and recommend effective, personalized solutions.
