I told my friend at the gym today that when I shower, I shampoo my hair, and then just wash with warm water everywhere else. He said this was weird.

Is this actually weird? What does everyone else do?

No.
As long as you are clean then its fine. Some people are retarded about cleanliness and think because they stink after 12 hours without a shower that everyone does.

If you worked a job with lots of grease and oil getting on you, or getting very dirty, then you would need to wash with soap. If you just get sweaty and not dirty then water is fine.

That said, its worth exfoliating pretty regularly for skin health.

My normal morning routine is: brush teeth > shave (head + face) > lukewarm shower with no soap > get dressed > go to work.
I still use soap once per week or so.

You should at least soap the essential parts
face, arse, pits, bollocks

No, I only shampoo. Soap is only necessary if you are especially dirty, like rolled in shit all day dirty.

You guys are some gross fucks. You actually walk around without washing your ass for a week? If you have access to a shower and soap, fucking use it.

Get in the shower, rinse myself everywhere with warm water, shampoo my hair, rinse that, shampoo my body, rinse that, take a cold shower for a minute or two, dry myself off.
I find the fact that you don't wash your body with a shower gel or shampoo or soap or whatever weird, but it doesn't matter as long as you're actually clean.

Haven't shampooed for like 2 years. I use body wash often though, I work a manual labor job and get fairly sweaty.

I use shower gel for my body with one of those exfoliation brushes, use a milder soap on my face and wash/condition my hair every few days. I've never really showered with just water but I don't think I'd really feel clean without using at least a bit of soap. it's down to you though, if you feel fine and don't stink then go for it.

id probably get out smelling like shit if I did this plus you shouldn't be shampooing that often nigga
