Can I find him if I feel itchy after staying in the hotel for one night?

The reason is not sufficient. Your itchy hair is not the only direct causal relationship with staying in a hotel. For example, if you eat something allergic, your body will itch, or if you sweat, you will itch when you see the wind. So don't look for a hotel, look for a hospital dermatologist. I hope it helps you. Thank you. .
