I was healthy, not overweight, just puffy nipples. I had gyno surgery at 23. Every since then I noticed my hair thinned. I shaved it and grew it out for the last year. Blood test is normal. My hair is now so thin in the front and thinning in the top back as well. Why, finally got rid of gyno after all those years and now this. Hair specialist said surgery probably cause it. I don't go out anymore.
