I haven't used this template in a while, but alternate version of that:

Well, at some point you start going down again, so no further than that.

Not even bald, but I tend to just do my whole head in one go.

Ages ago I ran out of shampoo and just used body wash instead... after a few weeks of being too lazy to buy more shampoo, I realized my hair was... completely unchanged.

So, fuck it. Water and body wash are my shower's only two ingredients, for the past decade and change.

I've got a shaved head and i just wash my face and hair at the same time. From the nape of my neck to the top of my head to my adam's apple and everything in between in one washing.

Same could be said of us bearded guys with hair. I just shampoo every thing from the neck up.

I asked this to my bald father once. Here's the gist of it.

With fancy facial cleanser? To more or less where the original hairline used to be.

Regular bar soap? To the crown. Shit gets oily.

Where no man has ever gone before.

I'm kinda harry so...when I shave my face, how far DOWN should I go?

Oh I can answer this! I stop when the tangent is > 45 degrees. Think Skyrim terrain logic. Everything else gets shampooed.

Northerlion has a pretty good bit about this

Rocking a skullet, my "face washing" goes to the hairline.

Since I use stuff that is gentler than regular soap on my face and other sensitive spots, I tend to use them on the bare areas of my scalp as well. Then again, I also tend to use really gentle shampoos too, so I could easily get away with using that on my face, I reckon.

But, yeah, in the shower I treat my scalp the same as my face, same products and such. When refreshing myself during the day, I use the same warm washcloth with no soap on the scalp too. Keeps things exfoliated well enough, and also keeps sebum from getting annoying.

All the way to the base of my neck. Especially in the summer

When I shaved my head, all the way.

Am bald. I wash my head just like I did with hair. And it runs down to the rest of my head.

Then I wash my body up to the neck

Anymore washing that has me break out in acne.
