This is interesting.That first article, Maritsa, really made me want to take a shower, too. Maritsa, you are going to suspect me of being EII when you see how into this health stuff i am. Most people find it boring or its just not appropriate conversation topic but since its the topic I will talk about it!
Kim's article is particularly interesting. I note that the article said that Sodium Laurel Sulfates (SLS) are the very worst. And yes, they are the
most common ingredient, and at the top of the list of the shampoos! I have been actively avoiding SLS for some years now. I do not use it in shampoo or soap (I use bars of goats milk soap) so therefore my shampoo/conditioner is more expensive. I use it sparingly (my favorite has a cherry-almond scent and I love it) and I have reduced daily shampooing to about 2x a week, which my hair adjusted to fine in the past couple of years.
I do shower the rest of me daily, and my shower head has a filter on it to filter out the chlorine which is bad to breathe and not good on your skin. Water-treatment-plant water is just not good for anyone. I use a 10-stage water filter for drinking water (the filter needs changing once a year), and I add to my diet extra minerals 3x a day which makes up for what was stripped from the water in all the processing (and because we ALL need them). I also take a product called 100+ Probiotics, 3x daily right now.
I
used to have notable dry skin problems I was always working on. I
always moisturized daily, and went for the natural products, and for the longest time, my go-to moisturizer was cold pressed virgin coconut oil, and that seemed a perfect solution. But then I developed a rash on my face that my naturapath determined was because of the coconut oil. He said yo never use vegetable-based oil, including that coconut oil, so I haven't used that for about 3 years now. Animal fat based things are the only thing we should use on our skin, he says, because it absorbs naturally into the skin. Instead, my coconut oil had been trapped on my skin keeping it from breathing, causing an underlying problem to not resolve itself, thus the rash). So I don't use anything now, most of the time. But recently I wanted to do something extra nice to prepare for my wedding, so I started using this amino acid mix some people take internally that his wife recommended I try, made from animal fats.
At any rate I have recently noted, now that spring is here, that the dry skin"condition that I thought was normal to me is truly completely
all gone. And that's pretty remarkable considering how long I had dry skin. I think its due to all those factors: no SLS's, taking extra probiotics and minerals daily, and also following my Naturapaths recommended diet as close as I can for over two years now which avoids carbs, a big culprit to many ills, and includes fats, even bacon and whole milk and butter! (I try to go for low processed of all of that, no-nitrate bacon, raw or lightly pasteurized milk, cheese from raw milk when I can).
Oh, and I also do not use deodorant.

I avoided aluminum in deodorant for years (not easy to do but I usually used that crystal rock stuff which is effective) and would never have dreamed there woudl ever be a day i did not use daily deodorant. But my naturapath has had me on a product I take 2-3x daily which has been key in balancing out my health and solving every ill - even keeps me completely away from any colds or flus for 2 years even though i work in schools and I used to get colds and flus a LOT. Its
this. That article, explaining this very simple and very cheap and very powerful therapy, is fair summery of it. As he said, physicians in our country who try to incorporate this therapy get harassed. IMO, this is clearly because no one will ever get rich on this, certainly no pharmaceutical company (and they run our medical system), because you cannot patent it, being natural, and its cheap. Sure, anyone can have (very temporary) adverse effects by taking too big a dose - one just adjusts dose to what one can take. At any rate, once I started on a protocol of this, which solved some serious problems I was aiming at, an unexpected "side effect" is no longer needing deodorant; it seems to kill off the bad smelling skin bacterias. That, perhaps along with the probiotics I take, have apparently eliminated the need for deodorant between showers.
Which is why Kim's article rings true to me. Though I do not want to give up showering! I like feeling fresh and clean. Though, when we move to my husband's house this summer, I will go from showering to baths. His (old) house has a big old enameled cast-iron bathtub, perfect for a deep soak, a luxury I love. (And its well water, so no more filtering is necessary). Where I live now we have a "water-saver!" tub, since this is a newer house, and that's how the newer tubs
are. Nowadays only wealthy folks who can afford high priced whirlpool baths get to have a full soak, while normal folk have to make do with a tub that, when full, won't even cover the top of their foot!
