Hair seems better today, despite the 70 dewpoint!
I'm sure that you should be able to find natural soap/shampoo bars where you use. Just be careful of the ingredients. You want soap made the cold process way--saponified oils (my hair hates castor oil, so I stay away from that.) They are more then cowashing, but gentler then lowpoo. Low porosity folks seem to like them better then others. They were really popular about 5 years ago, but feel out of favor because they are alkaline and hair is acid.
I did assess my own properties. Not really hard for me. My hair has always been fine. When I was younger, I was told that it was fine although there was alot of it. Now that I'm older, it's lost a lot of density (age, thyroid and a medication I take.) When it's short and there isn't a lot of it, and it takes 6 hours to dry with no product--that's low porosity.
I rotate products, so it's really hard for me to advise you on what to do. I wouldn't/couldn't use the same things all of the time.
