Thermal Spray 22 High Hold is for anyone who regularly flat-irons, curls, or roller-sets their hair and wants both heat protection and a firm hold that survives the styling process, not just protection during it. It's formulated for all hair types and sold as a professional salon-brand product, though it doesn't require professional application — it's used the same way at a salon backbar or at home.

Most heat protectants stop doing anything once the styling tool is put away, so a change of plans later in the day means starting over from wet hair. Thermal Spray 22 High Hold is built around Redken's Heat Restyling Technology, so the same application that protected hair during the original style can be reheated to reshape it later — useful for anyone who curls or flat-irons in the morning and wants to touch up or restyle by evening without redoing the whole process.

How you apply Thermal Spray 22 depends on the styling method:

• For flat-ironing or curling: mist onto dry hair section by section, using about 2-4 pumps per section depending on hair length.
• For a roller set: mist onto damp hair before setting, using slightly more product than the dry-hair application.
• Hold the can upright and mist evenly across each section before applying the heat tool.

• Pro: Rated for heat protection up to 450°F/232°C, covering the range of most professional flat irons and curling irons.
• Pro: Heat Restyling Technology means the style can be reactivated with a hot tool to refresh it between washes, without a full respray.
• Pro: Delivers a strong hold without the stiff, crunchy feel of a traditional aerosol hairspray.
• Con: Alcohol denat. is high on the ingredient list, which can be drying to hair and scalp with frequent, heavy use.
• Con: Not a natural or vegan formula — it contains beeswax and synthetic setting polymers.
• Con: It's a styling and heat-protection product, not a conditioning treatment, so it won't address existing dryness or damage on its own.
