This is why a dry scalp itches or flakes
The scalp is one of the most sensitive areas of our body. Unfortunately, it is often neglected. This can lead to problems such as dry skin, dandruff, or itching.
Like the skin on the rest of our body, the scalp acts as a barrier between us and our environment. It protects our body from moisture loss, pollutants, solar radiation, and microorganisms. When the scalp loses its natural moisture, the skin barrier can become permeable.

If the skin barrier of the scalp is permeable, local symptoms may occur. The most common problems include dryness, dandruff, and itching.
Signs of a dry scalp include unpleasant itching, a feeling of tightness after washing your hair, or visible dandruff. Very dry scalps can produce fine, white, dry dandruff that falls from the hair.
By the way: People who tend to have dry skin often also have a dry scalp
