I finally got to try this myself! I ordered a bunch of goodies from From Nature, With Love: powdered amla, shikakai, and bringhraj.
As per their instructions, and the recipes of herb-washers on the long hair board I visit, I mixed 1 tb. of each Ayurvedic herb, with 1 tb. powdered marshmallow root from my health food store (FNWL carries it, but it was cheaper locally) and 1c hot water (I used an infusion of sandalwood, for fragrance, although frankly the sandalwood didn't stand a chance against the smell of the herbs. It's not a foul smell, but it's very strong and ... different). I let it stand an hour. It was about as runny as commercial comditioner, not as gritty as I expected (the herbs are ground very fine).
I wet my hair down, squeezed the extra water out, and glopped in the herbal paste from scalp to ends, bent over the bathtub. Coiled it all into a big messy bun, wrapped a long flannel strip around my hairline to contain drippies, and put a plastic bag over it all. Went off to make lunch for ds and do my thing for an hour.
I rinsed it off upside down over the tub again; a few gritties were stubborn, but thorough scalp massage helped a lot. I did use some diluted cheapie conditioner to help kinda slick it out, but I'm not convinced it was necessary.
Unfortunately, I don't think I rinsed well enough. It takes a lot of rinsing and rinsing, and the kids were running around loose
. My hair was very soft, but it was kind of lank like it still had some conditioner on it. It might have been the marshmallow root; I've had run-ins with marshmallow-root mucilage on my hair before, and it does tend to coat. Next time I'll leave that out.
Anyway, it was interesting, and I'm going to keep tweaking at least until what I bought runs out.
