birth control
"I loved the shot as far as having no periods at all! But that was the only good thing about it. My hair fell out like crazy, lots of hair loss while brushing my hair, shampooing and just touching it. And it didnt stop. I have only had one shot which lasted for the 3 months and since day one of the shot my hair has fallen out. It used to be so thick, now my hair is thin. Not only hair loss, I had terrible terrible mood swings. Mad for no reason all the time. I have spoken to other people that took this and they said the hair loss never gets better, only worse. I did not gain weight, I was hoping to as I weigh 112, but I did not gain in 3 months time.  I am not going back for my second shot, the hair loss and mood swings is not worth it."
