I have hypothyroidism, and one of the side effects of this disease is always having dry, itchy skin. I use Curel (the one for really dry skin), Suave with Cocoa Butter and Shea Butter lotion. For us though, it is probably better to use a cream instead of a lotion because it takes time to absorb into the skin. You can also use Vaseline (I use it for a lip moisturizer) if nothing else helps. Good luck!
