I began having similar issues after the ovaries were removed...itchy, dry skin, painfully dry eyes, increased hair loss. No hot flashes, but I live in a warm climate, so maybe I just do not notice. Having been on T for three years already at that point, I was fairly certain it was due to the loss of the estrogen factories and not an allergen issue. My doc and I discussed upping my T dose a little, to see what would happen, but that caused some other undesirable effects such as polycythemia, hypertension, hyperlipidemia, etc. For my body, the dose of Testosterone is a delicate balance, and I must pick the lesser evils. I am back down to a minimal dose and things have stabilized, but the dry eyes are very unpleasant!
