I have had a flaky, itchy scalp since I had my son almost three years ago. Sometimes worse than others, including hair loss. I was unaware the problem was anything more than dandruff until I switched stylists and was told it was psoriasis. Stress could be involved, but I was wondering if hormone imbalance could be a culprate? I imagine I should just finally break down and see a doctor. Should it be my OBGYN?
