Common Causes of Itchy Scalp

  • Symptoms: Flakes on the scalp, hair, and shoulders, accompanied by an itchy feeling. For more information on dandruff and its causes, you can explore Svenson’s guide on dandruff treatments.

  • Symptoms: Red, greasy skin covered with flaky white or yellow scales.

3. Psoriasis:

  • Description: Scalp psoriasis is a common skin disorder that causes raised, reddish, and often scaly patches. It can be part of a more general psoriasis condition affecting other parts of the body. Learn more about scalp psoriasis and its treatment on Medical News Today.

  • Symptoms: Tickling feeling from movement of lice, itching, difficulty sleeping.

Treatments for Itchy Scalp
