When dandruff becomes passe' in the world of men's hygiene

I've been reading/hearing a lot lately about this underground trend in men's hygiene. It seems a lot of guys are voluntarily giving up washing their hair indefinitely - but at least for six weeks at a time- because after this time your hair will have found it's own 'oily' balance and will not require it anyway. Of course, the second reason is often the most crucial, and that perk is that non-washing is believed to spare your glands (or whatever they are) from being overstimulated, a possible cause for baldness. So for some men it has become a choice: the shampoo bottle and being a satellite receiver for pulling chicks (or however that t-shirt slogan goes) or a penny-pinching macho, with coiffed locks. Personally, I'd be loathe for Adam to give up shampooing. Why? 1) Non-washed hair stinks. It does. 2) I'd have no-one to mooch shampoo off when my own runs out and I don't fancy a nudie run to the cupboard to get another bottle- if there is one. 3) That would automatically place Adam in the 'I'm worried about losing my hair' category of male, and, please, I'm still just getting used to the fact he's THIRTY. What do you think? Have you heard about this new craze? (As far as 'crazes' go though, it's got to be said it's unique in not requiring to BUY into it). Would you want your partner to stop shampooing his/her hair??
