I am wondering why my eye brows have disappeared over the past two to three years. It seems that they thinned out to where they do not exist anylonger. Any thoughts on this issue, and will they come back naturally or not?

I have had a catact removed from the right eye about two years ago, and just recently I had surgery for diverticularitis, in October 2009. In June 2009 my family doctor referred me to a specialist for Thyroid problems. I also lost some hair on my head due to a combination of the anathesisa and anti-biotics I was given I would think that could be part of the problem in 10/2009, and I was not on any medicine for the Thryoid problem until April 2010. I am off of that medication now and I was just wonder if my eye brows will grow back or not. I was told that they could be a cosmetic implant that is sort of a tattoo that could be done, but I am not sure that I want to go that route or not. Just checking to see what you had on this issue and your thoughts about it. Thanks,
