There are many different types of scalp conditions that can cause symptoms such as itching, flaking, redness, and hair loss. Some of the most common scalp conditions include:

Seborrheic dermatitis:

This is a type of skin condition that causes red, scaly patches on the scalp and other areas of the body. It can be caused by a variety of factors, including hormonal changes, stress, and a weakened immune system. Seborrheic dermatitis is more common in men than in women.

Psoriasis:

Fungal infections:

Fungal infections, such as ringworm, can cause itching, flaking, and hair loss on the scalp. Fungal infections can be caused by a variety of factors, including poor hygiene and a weakened immune system.

Contact dermatitis:

This is a type of skin reaction that can be caused by exposure to irritants, such as hair care products, dyes, and chemicals. Contact dermatitis can cause redness, itching, and flaking on the scalp.

Scarring alopecia:
