[This review was collected as part of a promotion.] I have super fine wavy hair that lacks any volume unless I add in a curl defining cream. This is the first time I’ve tried a volume spray and it really did wonders! It instantly lifted my hair from the roots to the tips and gave it a bit of life. Love that this doesn’t leave my hair sticky or feeling oily which a lot of products tend to do.

[This review was collected as part of a promotion.] I’ve been using the K18 Volume Spray for a few weeks now, and overall, I’m impressed. It gives my hair a natural-looking lift without feeling sticky or heavy. The formula is super lightweight, and it doesn’t dry out my hair like other volumizers sometimes do. I also love that it adds volume while still keeping my hair soft and touchable, no crunchiness or stiffness. It works well with heat styling too, and I’ve noticed my roots look fuller after blow drying.
