one of our interns, a 23-year old guy has a very thick facial hair and he would show up every day with varying degrees of shave. I would only see him with a close shave once in a blue moon. probably he's also frustrated how expensive the blades are!
I bought several years ago an "expensive" blade that until now sits in my drawer. The thing is I only have peach fuzz on my face and I am already in my 30's
(I'm a guy)
I must have used the blades a couple of times just to find out how it feels to shave the face
