Anyone whose hair lies flat at the crown or part line and who blow-dries. KMS lists the hair type as straight to coily, so it isn't limited to fine hair, though flat, fine roots are where it earns its place most.

It suits both home users and stylists. The targeted spray makes it easy to work section by section during a salon blowout, and at home it works with a round brush or simply by drying with the roots lifted.

It is a styling product, not a treatment, so it won't address dryness or damage. Air-dry routines will get less out of it, since KMS's directions end with blow-drying.

Volume at the root is hard to get from products applied through the whole head, because anything heavy enough to hold also drags the lengths down. This spray is made to go only where lift is needed, right at the scalp, and to set that lift with a blow-dryer. Built-in heat protection up to 230°C / 446°F means the same step prepares hair for the dryer, which keeps the routine short.

1. Shake the can.
2. On towel-dried hair, spray close to the scalp for root volume, working in small sections for precise application.
3. For maximum volume, also spray into the lengths.
4. Blow-dry and style as desired.

Strengths

• Precise spray makes it easy to lift only the roots without stiffening the ends.
• Heat protection up to 230°C / 446°F covers the blow-dryer and most hot tools.
• KMS-reported results: up to 84% more volume and up to 6x more body vs. untreated hair, with root volume lasting up to 72 hours.

Limitations

• Contains dimethyl ether and butane as propellants; keep away from heat and flame while spraying.
• Designed around blow-drying; results with air-drying are not covered by KMS's directions.
• Contains polyphenylsilsesquioxane (a silicone-based resin), so it is not suitable for anyone avoiding all silicones.
• Fragrance includes limonene and linalool.
