I've seen a few charts that list properties of oils and butters and how they work on skin, but I haven't seen one for hair. I am able to get some things from forums and stuff but I am wondering if there is anything out there?
The first shampoo bar I bought had these ingredients and it turned my hair to straw unless I used an ACV rinse every other day: Saponified Organic Oils of Palm, Coconut, Olive and Palm Kernel (it had a few other things too)
Then I tried a shower gel with Saponified Organic Oils of Coconut, Olive & Jojoba. This was a bit better and brought my rinse to every other week or so.
Then I bought a Dr Woods Shea Vision liquid soap since I hadn't made my own yet. They don't have ingredients listed online but it seems to do even better.
I tried my own liquid soap for a couple of days and didn't like it. It was new though so I will try it again when I bring scents back out (all scents put away to see if my cat has allergies to them). I used mostly olive, but also some shea, coconut (10% I think) and castor.
After I did this I read a post somewhere that said that coconut is cleaning but drying - which I knew for skin - but the lightbulb went off and I said ok, I'll have to try another liquid soap with no coconut for my hair!
So this brings me back to my chart question - if there is something out there so I can research to see what ingredients would work well for hair and experiment and refine from there.
