The scalp itches when the weather is hot!

I think you must have oily skin. The hot weather and strong hair oil make your scalp itch. Human hair is divided into hard, elastic and neutral. Generally, neutral hair is better. In view of your situation, I think your hair must be elastic. Never scratch your head with your fingers when you itch to avoid bacterial infection. If you wash your hair every day and it still itches, I suggest you change your shampoo. Or choose traditional Chinese medicine reagents for treatment. You can also nourish your hair with bee flower conditioner after each shampoo. Intensive care. Or choose overlord, and the effect is good. I also suspect that your hair is allergic to the climate in the south. Don't take it lightly. I wish you a speedy recovery and return to your nature.
