I also had hair loss I did not notice it with the mirena as much, however when I was on the nuva ring I lost chuncks of hair I could not put my hair up because all olong the sides and in front under my bangs there was no hair left. It took a few months being off the nuva ring to notice an improvement. I then had the mirena for 5 weeks and now that I am closing in on 6 months post I have noticed a decrease in hair loss, while it was not nearly as bad as the nuva ring, I think all bc have an impact on our hair. I am so anti bc now! All bc's are similar, and all of them have the chance of giving you many different side effects. You could always try getting of the bc and see if the loss improves.
