If you’re looking for a hairspray that actually delivers on extreme hold without turning your hair into a crunchy helmet, OSiS+ #3 Session Extreme Hold Hairspray is a standout. From the first use, it’s clear this product means business—your style stays locked in place for hours, even in humidity or wind, yet still manages to feel surprisingly lightweight.
What really impressed me is the balance it strikes. You get a firm, reliable hold that keeps every strand where you want it, but without that stiff, flaky residue that so many strong sprays leave behind. There’s no visible buildup, and it brushes out much more easily than expected for something labeled “extreme hold.”
Another big plus is the fine mist application. It distributes evenly, so you don’t end up with wet patches or over-sprayed sections. This makes it perfect for both finishing a styled look and layering for more structured styles.
It also has a clean, salon-quality scent that isn’t overpowering, which is a nice bonus if you’re sensitive to heavily fragranced products.
Overall, OSiS+ #3 Session is a reliable go-to for anyone who needs serious staying power without sacrificing a natural feel and finish. Whether it’s for everyday styling or special occasions, it holds up beautifully—and that’s exactly what you want from a top-tier hairspray.
