Why does shampoo make my scalp itch?

An itchy scalp after using shampoo can be caused by harsh cleansing agents, such as sulfates, which remove the natural oils from your scalp, or by an allergic reaction to an ingredient.

That is why it is best to choose mild shampoos with ingredients such as glycerin, aloe vera, or chamomile extract, which cleanse the scalp without drying it out or causing irritation. Sensitive scalp? Try Care Scalp Sensitive Shampoo.
