Schwarzkopf Osis Flatliner is formulated with Hydrolysed Keratin, specially designed for daily use with heated hair tools up to 230°C. Reduces hair breakage and frizz, for super smooth hair with a light hold.

How to use: Spray on dry hair in sections before using heated styling tools, for smooth results without heat damage.

Tip: Flatliner can also be used as a blow-dry spray to amp up the volume! Spray into damp hair and blow dry - using a round brush will help add volume too.
