Overview
Kerastase's Nutritive Heat Protecting Spray is a leave-in for dry hair that combines heat protection up to 450 degrees Fahrenheit with plant-based proteins and niacinamide, aimed at reducing frizz and breakage on fine to medium dry hair rather than just shielding against styling tools.
This is framed as a nourishing step in a dry-hair routine, not a generic heat spray, so it's applied straight after shampoo and conditioner rather than right before styling. The ingredient list leans on plant-based proteins and niacinamide for moisture retention, which lines up with detangling and frizz reduction rather than hold or volume. At 5.1 fl oz it's a smaller bottle than most drugstore heat sprays.
- Leave-in spray applied right after shampoo and conditioner
- Heat protection rated up to 450 degrees Fahrenheit
- Plant-based proteins plus niacinamide for moisture retention
- Aimed at fine to medium dry hair prone to frizz
Who it's for
Suited to people with fine to medium dry hair dealing with frizz, flyaways, or tangles who want a nourishing leave-in rather than a plain heat shield. Less relevant for thick or oily hair types, since the formula is built around dry hair.

Performance notes
Kerastase directs applying it to clean, towel-dried hair right after shampooing and conditioning, working it into lengths and ends without rinsing it out. From there hair can be blow-dried, air-dried, or heat styled, with the plant-based proteins and niacinamide meant to hold moisture in through whichever drying method follows.
