What causes itchy scalp?

Answer

Itchy scalp can occur for a variety of reasons that range from improper hygiene to medical conditions. According to WebMD, eczema, scalp psoriasis and seborrheic dermatitis are three of the most common conditions that cause itchy scalp. Additional causes of itchy scalp include infrequent hair washing and dry weather.

WebMD relates that eczema is a skin condition often observed in infants, but it can occur in individuals of all ages. Eczema causes flaking and itching of the scalp, and the actual cause of eczema is unknown, but it can be linked to stress. Eczema is often treated with moisturizers and steroid creams. WebMD explains that scalp psoriasis is caused by an overgrowth of skin cells on the scalp, and it is triggered by an overactive immune response. Scalp psoriasis causes itching and scaling, flaking skin.

Seborrheic dermatitis is a common skin condition that can occur anywhere on the skin. When it occurs on the scalp, it is referred to as dandruff. Seborrheic dermatitis causes irritation, itchy scalp and flaking white skin. While the cause is unknown, WebMD explains that it is linked to an overabundance of malassezia, a fungus that is normally present on the skin. WebMD advises that it is typically treated with anti-dandruff shampoos that are available at most drug stores.

In addition to common scalp conditions, head lice can also cause itchy scalp. According to MedlinePlus, symptoms of head lice include severe itching of the scalp and oozing red bumps on the scalp and surrounding skin. Head lice spread through close contact with an infected person, and MedlinePlus explains that the condition is treatable with prescription or non-prescription shampoo.
