KÉRASTASE Nutritive Nectar Thermique Leave-In Heat Protectant 1.69 fl oz — 450°F Protection & Smoothness

KÉRASTASE Nutritive Nectar Thermique is a leave-in heat protectant cream that nourishes medium to thick dry hair, reduces frizz, and shields strands from heat up to 450°F while leaving hair softer and shinier.

This lightweight creamy treatment works between cleansing and styling to deliver instant detangling and long-lasting moisture. Formulated with plant-based proteins and niacinamide, it strengthens strand integrity, smooths the cuticle, and makes blow-drying and heat styling easier. Use it on towel-dried hair to protect from hot tools and to tame flyaways without weighing hair down.

How does this cream defend hair during heat styling?

The formula creates a protective layer around hair fibers to reduce thermal stress when using blow dryers, flat irons, or curling wands. Its heat resistance up to 450°F helps minimize damage from high-temperature tools, while conditioning ingredients preserve elasticity and shine.

• Heat protection rated to 450°F for styling versatility
• Forms a shield that limits moisture loss during heat exposure
• Supports smoother blow-drying with less friction and breakage

Will it make my medium to thick hair feel greasy or heavy?

No—the leave-in texture is designed to deliver concentrated nourishment without excess weight. Applied sparingly to lengths and ends on towel-dried hair, it detangles and smooths without leaving a limp or oily finish.

• Use a quarter-size amount for shoulder-length hair to avoid buildup
• Targets dry areas (mid-lengths to ends) rather than roots
• Drying and styling remain quick—no heavy residue

What ingredients restore and strengthen hair here?

Plant-based proteins provide replenishing amino acids for hair structure, while niacinamide helps retain hydration and improves overall manageability. Together they nourish the fiber for reduced frizz and a smoother surface that reflects light better.

• Plant-based proteins for fiber nourishment and resilience
• Niacinamide to lock in moisture and support long-term strength
• Conditioning agents that aid detangling and shine enhancement

How should I use this in my daily styling routine?

Apply to clean, towel-dried hair after shampoo and conditioner. Massage a small amount through lengths and ends, do not rinse, then blow-dry or let hair air-dry before finishing with hot tools as needed.

• Apply a quarter-size amount to damp hair; increase slightly for very long or thick hair
• Comb through to distribute evenly before heat styling
• Pair with Nutritive shampoo and mask for best results

Who is this for: KÉRASTASE Nutritive Nectar Thermique is formulated for people with medium to thick hair that tends to be dry, frizzy, or resistant to styling. It suits anyone who regularly uses heat tools and wants to reduce breakage, improve manageability, and achieve a smoother, shinier finish without heaviness. If your routine includes cleansing and a targeted mask, adding this leave-in cream gives thermal protection and everyday nourishment for healthier-looking hair.
