This product is kind of a holy Grail for me. I have a couple of complaints but overall the product really works.
PROS: This defines my curls lightly and without crunchiness. It's also not greasy, and while it doesn't have hold, I personally don't like hold, and prefer defined curls with lots of movement. I've repurchased for years and years, and it's never let my hair down, no matter what length (shoulder to very long). The best definition is on the first day, but it still looks fine on the second day.
CONS: The fragrance is definitely very strong - and I typically hate fragrance. But unlike most people here, it's funny how many friends and strangers have said that they love the smell of my hair. Ymmv of course. Even though I typically hate fragrance, and this one does last (though not at full strength, thank goodness), I don't mind it and actually have grown to like it.
The pump and packaging is not that great, and has broken when it's dropped in the shower. I'm also never quite sure when it's going to be finished.
USE: I have very long 3a hair and use about three pumps on wet, fresh from the shower hair. First pump is warmed and softened in my hands and then spread all over my hair. I then use pumps two and three to crush my curls upward. My head is upside down and I push the product into my hair from the bottom up, à la Devacurl style.
