Schwarzkopf Professional OSiS Session Extra Strong Hairspray - 500ml

OSiS Session is an iconic, professional-grade hairspray engineered for styles that demand maximum control, unyielding hold, and a flawless finish. Designed to lock down intricate updos, high-volume styles, and sleek runway looks, this extreme-hold formula sets instantly without weighing the hair down. It provides a reliable shield against the elements while remaining surprisingly easy to brush out when the day is done.

Key Benefits

• Extreme, Long-Lasting Hold: Provides ultimate structural support (OSiS Hold Level 3) to keep your style perfectly intact from day to night.

• Instant-Drying Formula: The ultra-fine mist dries immediately upon contact, preventing wet patches, stickiness, or clumps.

• Humidity & Frizz Shield: Forms an invisible barrier that protects your style against moisture, making it highly effective in humid and tropical climates.

• Flake-Free & Brushable: Despite its intense holding power, the spray brushes out cleanly and effortlessly without leaving behind any white residue or dust.

• Thermal Protection: Helps protect the hair fiber against heat up to 230°C/450°F and shields against environmental aggressors.

The OSiS Styling Technology

Schwarzkopf Professional utilizes an advanced resin matrix to deliver high-performance discipline without sacrificing the hair's natural integrity:

• Micro-Fine Spray Distribution: The specialized spray nozzle atomizes the liquid into a cloud-like mist, ensuring even, weightless coverage across the entire hairstyle.

• Film-Forming Polymers: Creates a flexible yet incredibly strong network around each strand, giving the hair memory and resistance against wind, motion, and humidity.

Simple How to Use

1. Style: Complete your styling routine using your favorite styling creams, pomades, or hot tools.

2. Mist: Shake the can well. Hold the canister approximately 30cm / 12 inches away from dry hair.

3. Apply: Spray evenly over the finished look in short bursts to lock it into place.

4. Pro Tip: For maximum volume, flip your head upside down and spray directly into the roots. To tame stubborn flyaways along a sleek parting, spray a small amount onto a styling brush or comb and gently smooth it over the hair surface.
