Sounds like Ron Jeremy's "problem."

i've heard that if you don't shower everyday then your hair will be healthier because it'll keep its natural oils, or something.

i've tried not washing my hair, but still showering so im not a slob, and instead of my hair feeling wonderful it actually feels pretty disgusting. it's not like it gets oily or anything, it just has a weird flat feeling, i can't explain it..
i think its obsessive compulsive. i'm used to showering every day, before atleast 2 or 3:00, if i do it later i feel gross.. and if i don't wash my hair i just feel like my entire day has been thrown off. i love showers. they're so relaxing.

yeah but you have to go through a period of a few weeks before that kicks in

Closer to a month, IME - did it once backpacking and then didn't wash it for like two years. It does require that you not be a hair-product user. Just rinse and brush routinely.

In places where there's no smoking in bars, (or there is smoking in work), you can go at least three days without showering.

I've got to have a shower every day too, but I only wash my hair once or twice a week when I'm not going to the gym...my hair actually does better on the 2nd or 3rd day after a wash

Haha! I often do the 'rock n' roll' lifestyle too... When I say I didn't have time to shower, it actually means that I could not physically get out of bed any sooner in order to take one. Like when I get 2 hours of sleep before having to be at work at 8am. I wake up at 7:40, brush the teeth, put on clothes, and get on the bike and go. And my hair fix is either pigtails or a do-rag.
