Some products never leave the styling station. For a lot of salons, Schwarzkopf Professional OSiS+ Volume Up and OSiS+ Session are two of them. That's why we now sell both as trios: three of the same product, so you can stock up once instead of reordering every few weeks.
OSiS+ Volume Up Trio (3 × 300ml) – $58.95
Volume Up is a volume booster spray for dry hair. It adds lift, body and bounce without weighing hair down, so it suits fine or limp hair that needs a boost at the roots. Spray it on dry hair, then tousle or backcomb for extra height. One can for the station, one for the shelf, and one spare means you won't run out mid-week.
OSiS+ Session Trio – from $58.95
Session is the extra-strong hold hairspray stylists rely on for updos, bridal and event work. It dries fast and the fine mist spreads evenly, so styles lock in without stiff patches. Choose the size that suits your salon:
Session Trio (3 × 300ml) – $58.95
Session Limited Edition Trio (3 × 500ml) – $64.95. The big can, times three, for salons that go through hairspray fast.
Why buy as a trio?
- You always have stock on hand for your best-selling products.
- You place fewer orders and spend less time reordering.
- It's the easiest way to keep your station and your retail shelf stocked at the same time.
