I have only used amla mixed with shikakai for cleaning, but I love it when used this way. My hair has gotten a lot glossier and my shed goes down when I wash with herbs. I got my method from someone on here, don't remember who. I put conditioner on my hair from about ears down (this is all out of the shower), then mix my shikakai and amla in an old honey bottle, more runny than a paste. I have found this is a lot easier to rinse out if it is mixed with more water. I can also get it all the way down to the scalp with less hair manipulation. I squirt it all over my scalp, pushing/sqooshing it down to the scalp area, then put a shower cap on. 15 minutes or so later I hop in the shower and rinse it all out, finished I am very happy with this routine.
