Made for fine-to-medium hair that gets regularly blow-dried or heat-styled and needs thermal protection built into the prep step rather than a separate product added afterward. It also suits anyone wanting a silicone-free, mineral-oil-free heat protectant, since it is formulated without either. It is a retail product usable at home; no professional mixing or application is required, though it is also used as a prep step in salons.

Its case rests on doing double duty as both a blow-dry accelerant and a heat shield in one lightweight mist, so there's no need to layer a separate silicone serum on top to get thermal protection. Because it skips silicones and mineral oil, it suits people who find those ingredients leave fine hair looking flat or weighed down after repeated heat styling.

• Mist onto clean, towel-dried hair from roughly 15-20 cm away.
• Comb through from roots to ends for even coverage.
• Blow-dry or heat-style as usual with a brush or fingers.

• Pro: States a specific heat threshold (230°C/446°F) rather than a vague 'heat protection' claim.
• Pro: Silicone-free and mineral-oil-free, so it will not build up on hair the way heavier silicone-based heat sprays can.
• Con: Alcohol Denat. is the second-listed ingredient, which can be drying on very dry or coarse hair with daily use.
• Con: Only a medium hold (3/5), so it is a heat-prep and light-hold product, not a hairspray for locking in a style.
