I am an oft user of dry shampoos. My hair is thin and fine and tends to get oily quickly; add that to the fact that I sometimes do outdoor performance where I way not get to a shower for a day or two, and you can see why I am a fan of dry shampoos.
I'm not a fan of spray dry shampoos, I've never used one that I've liked. I tend to use my own mixture of spherical microsilica and kaolin clay.
I rather liked the scent from this dry shampoo. It's definitely an herbal scent, but I enjoy that sort of scent. On my first go around with the powder, I wasn't impressed. I applied with with my hands as directed. It wasn't as effective as I would have liked it to be and it felt a little heavy. My next pass on it, I mixed in some microsilica and applied it with a large cheap make-up brush (like I usually use) and I was pleasantly surprised by the results. I would perhaps use this product to replace the clay in my own dry shampoo formula, but I wouldn't use it solo.
