I'll admit it, I am absolutely in love with glitter. That's just one of the many reasons I was drooling all over the makeup in the movie Sucker Punch - so many of the girls had gorgeous, glitter-encrusted eyes. Thus it should come at no surprise that whenever I see a glittery new product, I snatch it up as fast as possible.
Once dry, the glitter adheres to the skin fairly well, and unless you're constantly rubbing at the area where you applied it, it should stay for quite some time. I haven't actually used it on my hair because I don't typically wear glitter gels or temporary colors or things like that in my hair, and I would probably mess it up somehow. (Plus, my scalp gets dry in the winter and I don't want it to look any flakier than it probably already does.) But the gel isn't too thick, so it seems like it would apply to the hair nicely.
I deliberated this rating for a while - I wasn't sure if I should lower the score and reserve a perfect score for truly exceptional products, or leave it at a 5/5 because there weren't any real negatives for me to deduct points because of. In the end, I left it as is, because while it's not the single best product in the world, it still performs exactly as it is intended to.
Recommendation: The NYX Glitter Gel does everything it promises to do - not much more, but nothing less, either. I wouldn't say it's a must buy, but if you want something to add subtle sparkle to your everyday (or nighttime) makeup, this is a fabulous deal for $6. I would definitely recommend the Silver Lake color, since it is subtle, yet buildable.
