I use the tropical batiste which smells like a combination of hairspray and coconut.
I have long, dark, thick hair and this is good if sprayed on the roots and then brushed out. It also works well to remove outdoor smoke smells from the ends of your hair if you don't have time to wash your hair before you go out. The downside to this is that it dries out the ends and you'll need to smooth a few drops of hair oil over to de-fluff them.
First time trying this product I had great expectations as my hair tends to get oily quickly now so I wanted to stretch out my straightened hair into a few days. I found although it looks great at the start of the day and easy to apply, my hair seems to get oily and yuck by the end of the day. Maybe you are ment to keep applying the stuff all the time but I rather the clean feeling so for me it's for emergencys when I need my hair nice for an extra day and don't have time to wash it, but it's not a product I'd want to use for long between washes.
Tips: The pomegranate one (special edition) smells amazing!
