Ways to shave your cock

I have a recurrent scalp condition that I had to see a dermatologist for. He said to use a plain over-the-counter shampoo containing selenium or zinc. It worked fine, though "supply chain issues" mean that even though they’re common brands, I have to order them through the mail.

The selenium stuff seemed reasonably slick, so I thought I’d try it for shaving. It works as well as any of the shaving creams I’ve tried, but with one difference: no bumps or pimples afterward. I’m closing in on three months now, and still bump-free.

I have no explanation for it, but "it worked for me."

I always dealt with ingrown hairs and irritation whenever I shaved my shaft and balls.

I decided to try one of the at home “laser” hair removal systems which is actually just pulses of white light like a camera flash IPL for short.
You need to shave closely right before you use it, but if you keep doing it 2-3 times a week tapering down to once a week, the hair basically just disappears or maybe one in 50 hairs will grow back but it will be super fine and soft.

Anyway, the thing is, because it zaps your hair follicles, it seems to cauterize any little nicks and as a result, I get zero ingrown hairs or irritation, just a totally smooth shaft and balls like I just got waxed.

My shaft and balls take about 10-15 minutes to do per session, but I leave it on the same spot for 3 pulses of light, which are spaced at 5 seconds, so if your device is faster or if you only do a couple of zaps, it could be even faster.

I was always curious about those, but too sceptical to try. Which make and model do you use?

Is that the shampoo that is used for dandruff?
