Sean,

I feel your pain. My hair started receding at 18, I was desparate. I got transplants at 20, and that was a disaster.

My best advice is you HAVE to get someone in your family to listen to you. Tell them what you are thinking of doing and get them to help you with it. At your young age, you don't want to start an entire life hiding this from people you care about. It would be easier on you if you had some help with this. Ihope there is at least on person in your family that you can get on your side, maybe your mother?
