I've been taking 65mcg of T3 for a few months now , stopped NDT as wasn't converting ( had tests done ) . Felt much better , then not so good after a while and noticed bald patches around my ear area also body hair and eyebrows disappeared . I've just read a couple of posts on here saying low t4 can cause hair loss , also low eostrogen , I'm 70 so yes that's possible . I'm mortified , have started to add a little NDT again , but does anyone know if my hair will grow again ? Any advice very much appreciated !
