Q:

Why does my scalp itch?

A:

An itchy scalp can occur for several reasons, including scalp psoriasis, eczema and seborrheic dermatitis, says WebMD. According to Healthline, an itchy scalp can also be caused by tinea capitis or a head lice infection.

Tinea capitis, or ringworm of the scalp, is a fungal infection that is treated with antifungal medication, and head lice can be treated with over-the-counter medication to kill the lice and nits, says Healthline. Seborrheic dermatitis is a condition of flaking and itching skin that is referred to as dandruff when it occurs on the scalp.

Many cases of itchy scalp can be treated with over-the-counter shampoos that are specialty formulated for itchy, dry scalp or dandruff. In some cases, prescription creams may be necessary, says WebMD.
