I had a hair transplant one year ago (1300 FUE) in June 2015. They did the front and bald spot in the back. I don't feel like there's enough density in the front hairline right now. I don't expect to have the same hair I did at 16 years old but still. That being said, could I have a second one this year? Will more new hair grow in? I am in my late 20's and want to be cognizant that I may lose more hair. Thanks for your answers!
