Scalp conditions refer to various issues affecting the skin on the head, which can lead to discomfort and hair problems. Common conditions include dandruff, psoriasis, and seborrheic dermatitis. These conditions can cause symptoms like itching, flaking, and redness, impacting overall scalp health. Treatment options vary depending on the specific condition. Over-the-counter shampoos containing ingredients like salicylic acid or ketoconazole can help manage symptoms. In more severe cases, a dermatologist may recommend prescription treatments or lifestyle changes to improve scalp health and prevent recurrence.
