I liked the masculine aspect of getting a haircut. I liked it when they would shave the back of your neck with the straight razor and hot shaving cream, and when they put that waxy stuff in your hair if you had a crewcut...it had a distinctive smell.
I came across a small container that had been lost on a back shelf in my house, and upon opening it, the characteristic smell of it took me back 60 years.
Mine still does!
