Since '05 I've grown hair back 2 maybe 3 times for short periods, but I like it shaved. But there are options and choices for us all.
I'm actually rather wishy-washy. Of late (since some time in the hospital last month) it's kept at #2 guard and I'm OK with that. But there have slick dome times this past fall. I'm OK with that, too. Why this indifference? Well, my hair is (as I've said before in other posts) rather fine and white, and it's mostly temporal recession, no "horseshoe" or bald spot at the apex, and at nearly seventy, that'll never be my fate. No hair? Short hair? Even with hair (kept short), it's not easy to see that I have hair. Would not work for everyone. Your move.
I have a pretty full head of hair - except for a thinning spot in the back that hasn't really changed in 20 years. But I love having a shaved head, so once or twice a year, I shave it and keep it until the maintenance gets tiresome and then I grow some back - still usually a tight buzz.
For me, part of the fun of fully sly is the process of shaving a full head of hair, and another part of the fun is the anger of guys losing their hair, without the balls to go sly, who resent that I shave off hair that they'd kill to still have...
