I love Ayurveda. I've used other Ayurvedic products besides those just for hair, and I love it all. I've taken it upon myself to learn and research about the world of Ayurveda, so that I can educate myself on what herbs and Vedic products help which ailments. For those having probs with the powders, traditionally, Indian women use these powders AS A CLEANSER. That is why people are likely experiencing dryness, and marked dryness if they are shampooing before or after using these powders. Some can be hard to remove from the hair, but I've tried several, and they are all indicated as cleansers to be uses as a natural substitute for shampoo (brahmi, amla, maka/kapoor kachli I have used).
I mix my powders with heavy conditioners and oil, apply to wet hair, rinse, and follow with more condish. I haven't had probs with dryness; results are stronger, lightly fragranced hair. Brahmi is grainy, and it was so hard to remove from my thick hair that I decided to make it into a tea to spray/rinse my hair with. It made my hair strong after first use like a heavy protein treatment. Amla was easier to remove, didn't leave hair as stiff. Maka/Kapoor Kachli is the consistency of talc, a very fine powder. It was easy to rinse from hair, and I feel Kapoor Kachli works best on my hair...strengthened it like moderate protein, but it also felt moisturized, possibly due to condish I mixed with it, which had Babassu Mud in it.
