Itchy scalp

An itchy scalp is a common condition that can be caused by a variety of factors, including:

• Dandruff: Dandruff is the most common cause of an itchy scalp. It is caused by a buildup of dead skin cells on the scalp.
• Seborrheic dermatitis: Seborrheic dermatitis is a chronic skin condition that affects the scalp and other oily areas of the body, such as the face, chest, and back. It can cause redness, scaling, and itching.
• Psoriasis: Psoriasis is an autoimmune disease that can cause the skin cells to build up rapidly, forming thick, scaly patches. Psoriasis can affect the scalp, as well as other parts of the body.
• Eczema: Eczema is a skin condition that causes dry, itchy skin. There are many different types of eczema, and some of them can affect the scalp.
• Head lice: Head lice are tiny insects that live on the scalp and feed on human blood. They can cause itching and redness on the scalp.
• Allergic reactions: Allergic reactions to hair care products, such as shampoo, conditioner, and styling products, can also cause an itchy scalp.
• Stress: Stress can also contribute to an itchy scalp.
