Scalp disorders refer to various conditions that affect the skin on the head, leading to symptoms such as itching, redness, and flaking. Common types include dandruff, psoriasis, and seborrheic dermatitis. These disorders can result from factors like dry skin, allergies, or fungal infections, and they may affect people of all ages. Treatment for scalp disorders often involves medicated shampoos, topical treatments, or lifestyle changes. Maintaining a healthy scalp can also include regular washing, avoiding harsh chemicals, and managing stress. If symptoms persist, consulting a healthcare professional is recommended for proper diagnosis and treatment.
