Itchy scalp
Our hair needs a combination of vitamins, minerals, and trace elements to happily grow. If you didn’t know by now, zinc is one of the most essential trace elements, because it helps our body process carbs, fats and proteins, which are all the building blocks of hair. That’s why having low levels of zinc could damage your scalp.
Also, an itchy scalp can be linked with psoriazis. This inflammatory disease cause red raised scaly patches on the skin or scalp and is probably because of your genetics. In order to treat that, you need to get an over-the-counter shampoo that contains coal tar or salicylic acid.
