My tsh came back as borderline hypothyroid (something around 5.0 or so). I was prescribed 25 mcg of Levothyroxine. After a couple subsequent tests, it was still borderline and then I was prescribed 50 mcg. It is now down to around 3.0. My question is, I feel pretty much about the same, except my hair has fallen out more and has now become dry and brittle, and my scalp itches like crazy sometimes. My hair was in better shape before taking this. Has any one else had this problem? I am about ready to quit taking this to see if things improve. I'm starting to think I'm just allergic to this medication? Any ideas/suggestions?
