My daughter, who at 22 has never cut her hair ever, has been experimenting with no shampoo, vinegar rinses, olive oil, etc., with mixed results. Much depends upon hormones, hair type and diet. It is a better way to go, though. I think the soapless trend is also heavily affected by what a person eats, as well as availability of bathing water and opportunity to wash clothes. People who are heavy meat eaters I find have a very distinct body odor that comes through even with using soaps and which I find repellent. Like a walking hamburger stand. If one eats processed foods and works in a toxic environment, their skin will be sweating those toxins out and the acceptable scent level for being with other people won't be the same as, say, an organic vegetarian who doesn't use soap. Dirty clothing has a lot to do with acceptability; most people have encountered elderly people who absolutely reek because they wear the same clothes every day and believe that they don't dirty them and can't smell themselves. All those dead skin cells and poisons leaching from the skin end up in the clothes.
