My hair has been falling out excessively since around March this year, when I was taking 100mcg of levothyroxine only. Even when I increased the dose to 125mcg, then 150mcg, nothing helped. I was taking iron supplements to try to increase my ferritin but that didn't seem to help either. I was hoping that when I added liothyronine in September, that it would finally help, but my hair loss continued and maybe even got a bit worse! All of my other symptoms have completely resolved on liothyronine though so I was surprised the hair loss was still happening.
But the last couple of times I've washed my hair, I've finally lost a normal amount, much less than I have been for the rest of the year. I looked at my calendar and saw that I added the liothyronine about three months ago. I remember reading that hair grows in three month cycles, so could this mean that when I added the liothyronine, the hair I lost over the past month was from a previous cycle, and now maybe I've entered a new cycle that has been influenced by the extra T3 and is now happening in the normal way...?
I thought it would be helpful to post this in case anyone else is experiencing the same thing. It might be worth persevering with the hair loss!
