What is a scalp disorder characterized by dry?

One common scalp disorder characterized by dryness is known as seborrheic dermatitis, also known as dandruff. This condition is caused by an overgrowth of yeast on the scalp, which leads to inflammation, flaking, and itching. It often appears as white or yellow flakes on the scalp and can be exacerbated by factors such as stress, hormonal changes, and certain hair products.

Treatment for seborrheic dermatitis typically involves using medicated shampoos containing ingredients such as ketoconazole, selenium sulfide, or coal tar to help reduce inflammation and control yeast growth. In severe cases, topical corticosteroids or antifungal medications may be prescribed by a healthcare professional.

In addition to using medicated shampoos, it is important to maintain good scalp hygiene by washing the hair regularly, avoiding harsh hair products, and using a gentle shampoo and conditioner. It can also be helpful to manage stress levels, eat a balanced diet, and stay hydrated to help reduce symptoms of dry scalp.
