So, the hair dressers think people shouldn't shampoo every day. Not a real study, not real science, just anecdote and pseudo history, and open comments from everyone with an opinion. I'm sure there are many people, those with thicker, curlier, dryer hair than mine, with a good natural bristle brush applied, would do just fine washing their hair much less. But workers out in the dirt and weather, and those of us with thin, fine, oily hair, really like not having an itchy scalp.
Some of the skewed observations? That humans never before washed their hair daily. Didn't bathe daily either, but had skin diseases and parasites and itches. People in parts of Europe don't wash their hair every day. Neither did my mother, nor did I when I was a child, not allowed to. As soon as some gentler shampoos came out, and I was allowed to, my itchy scalp and stringy hair went away. A decent conditioner wouldn't come along for a few years, but that kept away the knots and tangles.
Oh, and how women would pile their hair on their head. Yes, and braid it and hide it under a hat. Daily brushing sessions, sure, for the middle to upper classes. The lower workers made do with much less, and weekly baths. Ever notice how little a problem dandruff is these days? Used to be ubiquitous. Simple daily washing away of dead skin works a treat. A few of the photos on Shorpy show how some women's hair used to look when washed rarely. Pretty obviously greasy, plastered down, and for many - stringy - as I remember my own as a child. The ones with thicker hair, different story. The directions from photographers taking school mug shots were not to wash hair that day. I had many ugly photos taken until I was responsible for my own shampooing, and ignored the instructions. May work just fine for kids with different kinds of hair, but for me, completely wrong.
Not to mention that I wash my OR hats every time I wear them, and I can smell which ones I've worn. I'm hardly going to go a day without washing my hair, since I am in close contact with patients. That area of skin doesn't need less cleaning, just because it's covered with hair, quite the opposite. At least for my hair.
I realize that different kinds of hair takes different care, and that is my point. I don't wash my hair every day because I'm told I must, but because I have discovered I must. Just as cats don't need water baths, but clean themselves and with a little brushing for the long hairs, there are probably people who could always just brush and that would be clean.
I do wish someone would do some genuine research into this. Because the anti-shampoo league is bringing out the Green stick of environmentalism. That makes me feel like I should reexamine my habits. But hairdressers? I've heard some ridiculous off the cuff advice from them, so that doesn't count as anything but irritation.
All for Green, but not for retro-nostalgic anti-clean.
