I got tired of bad hairdays due to very thin hair that wont do anything without tons of hairspray. I was getting my hair cut very short per a girlfriends request, but when my hair started thinning and receding... it made me look like I was partially bald due to the translucent nature of light colored hair.
So now, I just let it grow long, and ponytail it up. The thickness of the extra hair bunched up helps cover over the thinning spots, and it so easy to deal with. Brush back, tail up, and go. No more fighting with bad hair, no more sprays, no more expenses on cuts (except every once in maybe 3yrs).
Ive also thought about the straight razor thing too. But the startup expense to get into it is a little intimidating... as is the amount of skill to keep the bladed honed just right, so that they are both sharp and long lasting. Its also time consuming.
Currently Im using 3 bladed norelco shaver. (Ill look up the model later) Its doesnt chew up my neck like everything else does.. however, I believe that is part in fact due to the lower RPM of the motor. Which basically means, that it takes 3 times as long to get the entire job done. (and it never gets blade close obviously)
Disposable Razors tend to irritate my skin, making it glow bright red.
These type of razors are not meant to last. Made of cheap low carbon (probably stainless) steel... they will wear out quick.
I stupidly bought a cheap straight razor in Chinese shop once. Its blade is dull as a butterknife, and I can barely get it sharp enough to cut paper. (it wont cut my whiskers at all) Found out the hard way, that you need a high carbon steel blade to be able to sharpen them decently/more easily. I think only precision machines can get a decent edge on a S.S. blade.. and even then, it wont hold that edge like a carbon steel blade.
