Schwarzkopf Professional OSiS Flatliner Heat Protection Spray - 200ml

OSiS Flatliner is the professional’s choice for achieving ultra-sleek, pin-straight styles or perfectly polished curls without compromising hair health. Designed specifically for use with high-heat tools like flat irons and curling wands, this weightless spray provides an intense thermal shield while effectively controlling frizz and static. The result is hair that looks incredibly glossy, smooth, and healthy, with a long-lasting finish that stays sleek even in humid conditions.

Key Benefits

• Extreme Heat Protection: Formulated to protect the hair fiber against heat up to 230°C/450°F, significantly reducing damage, breakage, and split ends caused by hot styling tools.

• Ultra-Sleek Finish: Works to smooth the hair cuticle, creating a mirror-like, frizz-free surface that catches the light for an elegant, polished look.

• Humidity Shield: Acts as an invisible barrier to lock out moisture, ensuring your straight or smooth style stays consistent and doesn't "puff up" during the day.

• Strong, Controlled Hold (OSiS Hold Level 3): Offers excellent control, making it easier to glide through hair with a straightener and helping the hair "remember" its sleek shape.

• Weightless Application: The fine, non-aerosol spray distributes evenly without leaving behind any heavy, oily, or sticky residue.

The OSiS Styling Technology

Schwarzkopf Professional engineers Flatliner to marry high-performance styling with advanced fiber protection:

• Advanced Polymer Matrix: Creates a protective layer around each strand that stands up to high-temperature contact, preventing moisture loss and structural degradation.

• Smoothing Agents: Carefully calibrated to provide the necessary "glide" for straighteners, reducing friction and preventing snagging during the styling process.

Simple How to Use

1. Prep: Mist the spray evenly over dry or damp hair before using hot tools.

2. Section: Work in small sections, applying a light mist if necessary, then immediately follow through with your flat iron or curling tool.

3. Glide: Use a steady, fluid motion when straightening to ensure the product is evenly heated and the hair is perfectly smoothed.

4. Pro Tip: For maximum sleekness, use a fine-tooth tail comb in front of your flat iron to ensure every strand is perfectly aligned before the heat touches it.
