I might be a little biased. But then again, I was one of the heads of hair this product has been tested on for years. Now we have 25,000+ customers and they seem to like what we've done with things :) It's a funny thing to get used to at first - it doesn't lather and it doesn't strip your hair clean like shampoo does, but the end result is probably one of the best hair days ever. And you can just keep on having them over and over and over.
The support team are amazing. They give real, human responses to issues and genuinely care about doing right by the customer. At $22 it definitely isn't the cheapest hair wash product out there - but it seems like a lot of people think it's really worth it. Plus it gets cheaper if you order a refill pouch down the road!
