Hi:I have suffered from dandruff most of my life, it is worse on the hairline close to my forehead, sometimes I bleed from scratching too much.  Recently, I have noticed that my forehead has become very dry with patches.  I was also scratching these patches but stopped when I noticed that it was leaving white skin.  Now I have white patches on my forehead.  Is this due to dandruff or dry skin?Please Advise
Namaste Greetings of the day Welcome to Chat Doctor The white patches are most likely due to seborrhea dermatitis due to Dan Chat Doctor.  Applying ketoconazole shampoo will help.  Take care Regards
