Heat protection matters most when you use heat, but some of these do more than that. Serum Chroma Thermique also helps shield hair and colour from UV and humidity, so we suggest it for coloured hair even on air-dry days, especially before the beach or pool. Lotion Thermique Sublimatrice detangles and smooths flyaways whether you blow-dry or let your hair dry naturally.
Check the rating against how you style. Serum Chroma Thermique is made for hair that is blow-dried, straightened or curled, and like Nectar Thermique and Lotion Thermique it protects up to 230°C. Résistance Blow-Dry Primer is rated to 180°C and is designed around the blow-dryer, so if you use hot tools at higher settings, pick one rated to 230°C.
Towel-dry first, then apply section by section so the underneath gets protected too. Comb it through before the brush or dryer comes near it. Keep the nozzle pointing down the hair shaft. On thick hair, rough-dry to about 80% before you pick up a brush, which cuts drying time. On weakened hair, lower heat for a little longer is kinder than a fast, hot blast.
Three more Kérastase products double as heat protection. Curl Manifesto Crème de Jour Fondamentale protects curls up to about 230°C when you diffuse, Gloss Absolu Spray, $63.75 (RRP $85), protects long, frizz-prone hair up to 230°C, and Première Filler Fondamental Serum protects damaged, bleached hair up to 230°C and repels humidity.
