I wanted to love it

Works great, my hair looks so well after use. One complaint though is the lift doesn’t last. A little bit gritty like an expensive hairspray but overall great product just not sure if I will repurchase right away. For the price, I say skip it. I didn’t return it though

smells great, wheres the volume?

smell is amazing, it seriously smells so good as most K18 products do but i’ve gave this spray chance after chance and i’m searching for the volume… want to love this product so bad but after spraying generously and using most of the bottle, sadly does not work.
