A few more things I'd like to log,
I started taking lukewarm showers and washing my face with cold water about 3 weeks ago. I'd always used semi-natural soap, but it still had a lot of sulfates etc. in it. This past week I didn't use any soap on my face. My face got excessively dry and flaky. Last night I used a natural soap on it (safflower, palm, and coconut oils, oatmeal, honey, some rosemary extract) and today it is much less dry and has a less flushed color.
As for shampoo, I'm using semi-natural stuff, it's 80% aloe and pretty much 20% nasty chemicals. It's a big bottle, but when I use it up I'm going to try Dr. Bronner's next.
