I started losing my hair at 21, and have noticed it happenng with blokes my age, I shave my down to a skin head now.
Blokes your age Mid 30's yes a slight withdrawal of the hair line is acceptable
But Sorry to say this LV 19 - 22 year old are going Bald
I'm rolling on 39, yes I have a bit of thinning going on but still have a good Hair line
At work it's quite funny like I said I'm in my late 30's ans the other older Tech is in his mid 50's yes a lot of gery hair
but both still full hair lines
The two others are early 20's and they are in a race to see whos fringe can get to the back of their neck first
