Hi,
i am 37 years old and after a some years of trying to hide my balding with hats and combover-ish haircuts, i decided to shave my head. I let it grow out a few mm, but i much prefer the look and feel of a smooth shave, also my hairline has moved too far up for the buzzed style.
Unfortunately, most reactions haven't been so good, maybe i'll write about that in another post. I for one am perfectly happy with my decision.
