Phytodefrisant by Phyto is amazing for what you're looking for. It's pricey, but I can honestly say it's one of the FEW beauty products I'll pay that much for and happily. I also like the idea of using plant mucilage on my hair, lol!
Seriously though, my hair comes out frizz free, silky, shiny, and full of volume (using a round brush and blow dyer of course)!Use some velcro rollers for extra 'wow' volume. And it does NOT weigh my hair down. There are silicone serums and blow drying cremes that give the same shiny silky result but sacrifice volume or it'll make my locks get greasy quicker. With phytodefrisant, I can extend the length of my blowout longer than I could using any other product.
The tricky thing is figuring out how much to use. Too much, and your hair can get a 'tacky' or 'filmy' feeling. Too little and you won't notice much of a difference than if you didn't put any on at all.
hth, it really is worth checking out IMHO!
