Hair loss at 24, what should i try? With pics

[jellyman]

I've always had the hair swirl thing on the back of my head which makes it looks like you have a bald spot but its been getting bigger over the past year or so. My dad started balding at his crown around 24 as well so it makes sense. My question is what treatments should i start with. My hairline might be receding a bit but i'm not really too worried about that.
