HELP. How can stop my receding hairline?

I just turned 15 a month ago and my hairline is receding, I THINK. Last year, my friend noticed my hairline, and said i was going to be bald when i get older, because of my receding hairline.





I've just seen my mom's dad a couple of months ago while he was visiting and I noticed that he was sort of bald.





I don't want to be bald when I get older, so PLEASE tell me if there is ANY way to slow or stop my receding hairline? I spike my hair up almost every day, but there is almost no way I am going to stop that, and I don't look good, at all, with a buzzcut. I've heard horse shampoo or something like that can slow it down. But that might be for something completely different.





I know that my hairline is messed up because on the top-sides of my hair, it caves inward on my head, if you look at the front view of my face/head. I also have a widow's peak, but I'm not sure if that is the result of receding hairlines... HELP.HELP. How can stop my receding hairline?
you can waste your money on a lot of products that claim they can grow your hair or keep it from receding. but hair loss has a lot to do with your genes for the most part and its nothing you can do about that but get some nice hats.HELP. How can stop my receding hairline?
