I carried a pocket comb during my school years out of some misguided illusion that when I combed my hair I was actually doing something good. There was nothing thick or manageable or interesting about my hair, ever. I know I tried one or more of those products, but don't remember if I ever used one regularly. If nothing was around, I'd use water in a futile attempt to make the hair go where I wanted.
I well remember the barber always splashing something on there, and the way the hair would feel walking out after a haircut and for the following day or so.
Hmmm, still thinking about the pocket comb. I'll bet I carried one longer than I care to remember. Maybe best leave it at that! What with male pattern baldness developing early (or it seemed early for me), I did breathe a sigh of relief at whatever point it was I gave up all pretense and just kept the top clean and smooth. Yuck. I really don't like my own hair memories. Maybe I'll find a few pieces of photographic evidence to post later.
