Suggest Remedy For Dry And Thinning Hair

I have hep c. I have for 20+ years. I tried to take some medication for it a couple years ago, but could not tolerate it. In the last 6 months or longer I have been noticing my hair is very dry and seems to be thinning, ny nails are curving downward and also thinning. In the past few weeks my skin has become very dry and ichy, to the point I have tiny bumps and dry patches on my back. Also I have some topical pain in the to of my head. It s like a burning feeling or like a sunburn feeling. And some pain to the touch under my right jawbone. Could any of this be related to the Hep C?
