This spray is for people who regularly use a flat iron or curling iron on dry hair and want one product that both preps the hair for the heat tool and finishes the style afterward. It suits most hair types that tolerate heat styling, including restyling second-day or unwashed hair rather than starting from a fresh wash.

The main draw of this spray is that it replaces two separate steps, a heat-protectant priming spray and a finishing spray, with one product. The polymer in the formula is designed to respond to heat, so applying it before flat-ironing or curling helps the style hold, and misting it again afterward adds shine and hold without switching to a different product.

Use only on completely dry hair, since the formula relies on heat from a styling tool to activate.

1. Section dry hair before styling.
2. Hold the bottle about 15-20 cm (6-8 inches) from the hair and mist each section.
3. Style the section with a flat iron or curling iron as usual.
4. Once all sections are styled, mist lightly over the finished look to add hold and shine.

Pros

• Functions as both a heat-styling primer and a finishing spray, so it replaces two separate products with one.
• Light, flexible texture is built not to leave hair feeling coated or stiff.
• Formulated to help reduce thermal damage and breakage from repeated hot-tool use.
• Works for both straightening and curling rather than being limited to one style.

Cons

• Only intended for dry hair, so it isn't a wet-hair styling primer.
• Needs heat from a styling tool to activate; it does little on its own without a flat iron or curling iron.
• The line has been discontinued by the brand, so once current stock is gone it won't be restocked.
• Ingredient lists for this product line include Alcohol Denat., which can be drying with very frequent use.
