Finally, my scalp problem was solved at Jeon Dermatology Clinic in Chungcheongnam-do.

I frequently developed gray hair, so I dyed my hair every two weeks. My scalp started burning and itching, and the dead skin cells started falling out in thick flakes like dandruff, so I went to the doctor. I wouldn't have had to dye my hair, but since I work in the service industry, I couldn't avoid it. So I explained the situation to them. After examining my scalp, they prescribed shampoo, oral medication, and topical medication for dermatitis.
I've heard that steroids aren't good for your skin if you take them for a long time, so I asked them to make a mild one for me. They really did make one for me and even reassured me not to worry too much! After about two days, the dead skin cells had definitely decreased and the burning sensation had disappeared. They made a product that was right for my skin, so I highly recommend it!
