youre only 18 dean? i know how you feel, im only 20, and going to school just sucks. I usually wear a hat, cause for obvious reasons, but on days that i dont, i use toppik, and holy sh*t that stuff works. I didnt think it would, but its perfect for me. i dont know if you tried it, and im not sure if you could get it less than the 20$ small bottle, but i recommend giving it a try. If only they had samples...
BTW have you seen a derm? you sure your suffering from male pattern baldness? I know alot of people here will be like "No dude its male pattern baldness just live with it cause i have to and its not fair if you dont have male pattern baldness" but definitely get it checked out.
And contrary to what that one moron said, i doubt your hair follicles are dead.
