Metropolis Nano-9 Thermal Guard

Have only used this product a couple times, so I'm not sure on it's effectiveness on protecting my hair. I bought this because it had good reviews. I have only sprayed it on my dry hair, before curling it. I find it leaves a greasy appearance, which I don't like. Also, the bottle is very small.

I loved the way it made my hair feel and the shine it gave it. The bonus is that it smells fabulous also!
