OSIS+'s Session is a hairspray that provides an extra strong hold without leaving flaky residues or a stiff feel. The formula protects against humidity while adding a healthy shine.
Extra strong hold Protects against humidity Brushes easily Long-lasting Adds shine Thermal protection up to 230°C/450°F
What It Is
An extra-strong-hold hairspray that doesn't behave like one. Session delivers serious, long-lasting hold, but without the flaky residue or board-stiff feel that usually comes with maximum-hold sprays — it stays brushable, so you can restyle rather than being locked in. Fast-drying, humidity-resistant, and it adds a healthy shine. Vegan. The finishing spray for styles that genuinely can't move.
Hair Concerns
- Frizz
Key Benefits
- Extra strong, long-lasting hold. Brushes out clean — no flaky residue, no stiff feel. Fast-drying. Protects against humidity, wind and heat to 230°C. Adds healthy shine. Vegan. For any style that needs to hold all day.
Highlighted Ingredients
What Else You Need to Know
The brushable-but-strong combination is the trick most hairsprays miss — you get extra-strong hold that you can still comb through and restyle, instead of a helmet you have to wash out. Fast-drying matters more than people think: a spray that dries slowly lets the style drop before it sets. Vegan. Authorized Schwarzkopf Professional retailer. Earn Beauty with Benefits points on every purchase, redeemable in-store and online.
Fragrance
Signature OSiS+ fragrance. Contains parfum.
How to Use
Hold about 30cm from dry, finished hair and mist evenly. For maximum hold, build in light layers rather than drenching in one pass. Brush through to restyle whenever you like — it won't flake.
