Early onset hair loss

Anyone have any trouble with this? I know there isn't much you can do honestly except learn to accept it and probably shave your head but I'm just curious to know if anyone else is going through it. I can't lie and say that it doesn't mean anything to me, it has had quite a profound effect on my self image.. but I'm starting to get over it. Kinda just like oh well at this point. Bound to happen to like 80% of men, but at such a young age it kinda takes a toll. I'm only 18 for anyone curious.

I'm a Norwood 3:

Have a dermatologist appointment coming up in the next couple of weeks I think. He's gonna tell me the cause of my hair loss, hopefully. Then I can go from there.. but i honestly dont see anything being too effective.

 

I have what I call a receded hairline. I didn't start noticing it till i was about 15. It hasn't gotten worse but to give you a good idea, my hair doesn't start for about 5 inches above my eyebrows..I cover it up with long hair, but If I pull it back my hairline looks more noticeable and weird. Uneducated neighborhood morons say I have a big forehead.
