Love, love, love this glitter hairspray! Wish it came it "autoship" because I wear it every time I go out. I get so many compliments on it. Everyone loves how my hair just "glitters"! You can use almost til bottom of can and lasts a long time. Just love the colors and wish it came it more colors. Great product!

Horrible smell

Bought this to use on my hair smells so bad. I can’t even use it. The consistency is not my favorite. The glitter is too fine. Will look for a better product next time. Would definitely not buy again

Great hair/body spray

Sprays on easily and evenly haven’t had any issues with clogging. Has no smell and great even consistent sparkle. This took awhile to be delivered but overall happy with this purchase. Did not wash off in pool but washes off in shower easily.
