Thanks, KathyMack. I think I've read all the threads now. I haven't seen anyone compare rhassoul with bentonite as a face mask (I see Misspam likes the rhassoul for her face and hair); so in the interests of science, I've gone ahead and ordered the rhassoul clay.
I also just bought my first amla, shikaikai, and other ayurvedic powders. When I was at the grocery I saw the Swastik shikaikai shampoo bars that you've written about, so I picked one up. Can't decide what to try first! I see that you moved on to other bars you liked more pretty quickly, but I haven't used any shampoo bars yet, and this one was there, and cheap, so what the heck. I almost never low-poo, my hair & scalp seem to do fine with just co-washing & such, so I don't think shampoo bars are going to be a regular thing for me, but I figure I'll try the Swastik bar at least and see how it goes. But first, I think today I'll try the shikaikai powder. So many options, so little time!
