Hi Fox,
In all honesty, I don't think you need a hair piece yet. You've still got a lot of thick long hair. True, you are experiencing some recession but with the comb forward hair style it's covered up. You only notice it when you hold your hair back. There are probably a thousand people reading your post and thinking 'I'd kill to have his hair!' Recession is natural and 'age appropriate' as your face changes with age. As you age facial features become more angular and the the hair line naturally recedes. There are obvious exceptions to this like Bill Clinton. Clinton has no recession but he's a great example of an exception. But really, if you're wearing your hair combed forward the recession is not an issue.
Regards,
John
