Hm... at 50 isn't it too late to start worrying? Trying a new treatment

[UncleVito]

I just saw so many really young guys with hair loss problems posting here... I'm a newbie on forums..., but not in life, heh)) I'm already 50 and start to get bald some 5-6 years ago, before that didn't sport very thick hair as well... But at least some hair... Actually, two questions - don't you think it's too late to begin fighting my baldness at 50? Maybe it's already natural causes?... I don't know...
And the second question - I just started a new treatment, called Xeno Laboratory, it's a serum - they claim it does help. I just started it, anybody already tried this product? I bought it when I was Ukraine this summer, my buddies there recommended it as very effective (and it is also manufactured there). I also saw it here in the US at www.xenolabusa.com
Will be updating.
