One thing that is inescapable with CH is the dry skin and hair. Even when Bug is on the proper dose of levothyroxine her skin and hair is so dry. She drinks a lot of water and take omega-3s every day. We treat her skin with Cetaphil because it's so dry and she's so sensitive. And for her hear we use Moroccan Oil treatments, but not matter how much cream/oil it is still so dry and brittle.
We've been dealing with this now for 7 years so I doubt it's going to change any time soon. I just wish everything wasn't such a challenge.
