True rating: 2.5. I want to start off by saying that in my opinion this is exactly the same as the Pantene Blowout Extend Dry Shampoo. I've used both and didn't notice any difference between the two.
This product works, but it's not great. I have really oily hair so I've tried a lot of dry shampoos, and this isn't one that I see myself purchasing again. The product sprays out very wet and you need to wait around for it to dry before you can rub it into your roots or brush it through. If you're in a hurry and you try to rub it in while it's still on the wet side, you're gonna make your hair look even greasier. Usually I'd spray it and then go make coffee or start on my face makeup while it dries. It's annoying (especially if you're in a hurry) but that's not a deal-breaker for me as I've found many dry shampoos spray out wet.
Once this is all rubbed in and brushed out, it does absorb the oils well and it does add a tiny bit of volume. However, you can tell you have dry shampoo in your hair. I have blonde hair and this leaves a white cast on me, so I'd really beware if you're brunette or darker. Being totally honest, sometimes I like when dry shampoos leave a bit of a white cast because if my darker roots are growing in this will lighten them up. ;) But this stuff makes it too obvious. It looks chalky and powdery in the hair. It also leaves my hair feeling slightly stiff and sticky, which I don't like.
My number one issue with this stuff is the scent. It smells like pretty much every other Pantene product I've ever used -- that fresh, clean, kind of soapy smell. But this stuff is STRONG. Like, literally choking on it if I breathe while applying it, scent lingers in your bathroom for hours after using it strong. I can smell it on my hair all throughout the day. It's just obnoxiously strong. If you're one of those people whose hair gets smelly when it gets too oily, maybe this will be nice for you to really cover that up. But for me, it's just way too much.
There are dry shampoos at the drugstore that perform (and smell) way better than this. I did use up my can, but I won't be picking it up again.
