Receding Hairline

[Zuck]

I am 19 and I first started noticing that my hairline was going backwards about 18 months ago. It's not totally terrible at the moment, but it's certainly not ideal either.

Both my father and my his father are bald or going bald on top, but they weren't at my age.

I'm a student, so surgery is out of the questions. Plus I don't much fancy walking around with a skinhead and the red patches on my forehead.

So, I'm looking for a product or products that will help regrow my hairline (if it's even possible). I know there are a lot of hair products out there, so I don't really know where to start.

Thank you.
