KÉRASTASE Curl Manifesto Crème de Jour leave-in cream 5.07 fl oz — defines curls, controls frizz & heat protectant

KÉRASTASE Curl Manifesto Crème de Jour Fondamentale is a lightweight leave-in cream that hydrates, defines and controls frizz for wavy, curly and coily hair while providing heat protection up to 450°F.

This daily cream-by-KÉRASTASE is designed to be applied to towel-dried hair to boost curl definition, improve detangling and add moisture without weighing strands down. Formulated with Manuka Honey for hydration and Ceramide to strengthen the hair fiber, the Crème de Jour Fondamentale fits into the Curl Manifesto regimen as a styling and protective step. It aims to reduce frizz for up to 24 hours and supports heat styling or diffusing by offering thermal protection.

How do I use this cream to get defined curls?

Apply the leave-in to damp, towel-dried hair, working section by section so the product spreads evenly from roots to ends. Rake through and scrunch each section to encourage curl formation, then let hair dry naturally or use a diffuser for added volume and shape.

• Work a generous amount into wet, towel-dried hair.
• Distribute product evenly from root to tip.
• Rake and scrunch sections to form curl pattern.
• Do not rinse; air-dry or diffuse as preferred.

Will this cream keep my curls frizz-free and safe from heat?

The formula is engineered to control frizz for up to 24 hours while providing thermal protection for styling tools and diffusers up to 450°F. It helps smooth the hair surface so humidity-induced frizz is reduced and helps protect strands when heat is used to style.

• Instant frizz reduction lasting up to 24 hours.
• Heat protection compatible with styling up to 450°F.
• Smoothing ingredients help resist humidity and flyaways.

What measurable benefits can I expect when using it in the Curl Manifesto routine?

When paired with other Curl Manifesto products, the crème contributes to visibly more conditioned, defined and manageable curls. Independent-use results will vary, but within the system you can expect improved conditioning, easier detangling and stronger curl structure.

• Up to 74% more conditioned curls within the regimen.
• Up to 98% improved detangling power with system use.
• Up to 72% more definition and 76% stronger curls using the full routine.

Is this product suitable for all curl patterns and hair concerns?

The Crème de Jour Fondamentale is formulated for a wide range of textures — from loose waves to tight coils — and focuses on moisture, definition and strength rather than altering natural pattern. Because it’s ultra-lightweight, it won’t heavily weigh down finer curls but still delivers slip for detangling thicker textures.

• Works on wavy, curly, very curly and coily textures.
• Lightfeel formula suitable for fine to thick curls.
• Intended for hydration, frizz control, detangling and heat protection.

Who this is for: KÉRASTASE Curl Manifesto Crème de Jour Fondamentale is aimed at people with natural waves, curls or coils who want a versatile daily leave-in that nourishes and defines without heaviness. It's a good pick for anyone seeking improved manageability, reduced frizz during the day and protection when styling with heat, and it performs best when used as part of the Curl Manifesto collection.
