What is Schwarzkopf OSiS+?
OSiS+ is Schwarzkopf Professional's salon styling range — a complete toolkit for creating and finishing a look, from matte, lived-in texture to glassy shine and from flexible, brushable movement to concrete, all-day hold. It's a salon-floor staple because the products are built to be layered and because the finishes are predictable: you can reach for the same product and get the same result every time.
The OSiS+ range by job
| Job | Products | Finish |
|---|---|---|
| Hold (hairspray) | Session, Freeze, Elastic | Extra-strong, strong and flexible hold |
| Hold (gel/mousse) | G.Force gel, Grip mousse | Strong to extreme structured hold |
| Texture | Dust It, Thrill, FlexWax, Mighty Matte, Mess Up | Matte grip and definition |
| Volume | Upload, Volume Up, Refresh | Body and root lift |
| Shine & finish | Sparkler, Glow | High shine, anti-frizz |
| Heat protection | Flatliner, Hairbody | Pre-styling protection |
Which OSiS+ hairspray should you use?
- Session — extra-strong hold for long-lasting, set styles and finishing work.
- Freeze — strong hold with a workable finish; also available as a pump spray.
- Elastic — flexible, brushable medium hold for movement that lasts.
As a rule, the more movement you want to keep in the finished style, the lighter the hold: Elastic to keep it soft and brushable, Freeze for everyday strong hold, Session when it needs to stay put.
What is OSiS+ Dust It?
Dust It is the cult mattifying volume powder — a fine powder sprinkled at the roots (or worked through mid-lengths) for instant lift, grip and a completely matte, touchable texture. It's a go-to for fine hair that won't hold volume and for building gritty, undone, textured looks. A little goes a long way: tap a small amount at the root area and work it in with fingertips.
Texture and finishing
For texture and definition, OSiS+ covers every finish: Thrill fibre gum for pliable, stringy definition, FlexWax for ultra-strong cream wax, Mighty Matte for strong matte control, and Mess Up matte paste for undone separation. To finish, Glow anti-frizz serum smooths and adds shine on mid-lengths and ends, while Sparkler shine spray gives an all-over gloss.
Volume and body
For lift and body, Upload volume cream and Volume Up booster spray build root volume before drying, and Refresh bodifying dry shampoo revives and adds texture between washes on the salon floor or at home.
Does OSiS+ include heat protection?
Yes — Flatliner is the OSiS+ heat protection spray, applied before straightening or heat styling to shield the hair and give a sleek finish. Hairbody style & care spray also supports the style with conditioning benefits during blow-drying.
How do you layer OSiS+ in a styling routine?
- Prep on damp hair: apply a volume or heat-protection base — Upload or Volume Up for body, Flatliner before heat.
- Build texture when dry: work in Dust It at the roots or a wax/paste through the lengths for grip and definition.
- Finish: set with the right hairspray for the look (Elastic, Freeze or Session), then add Glow or Sparkler for shine if needed.
