KÉRASTASE Curl Manifesto Crème de Jour Fondamentale Leave-In Cream, 5.07 fl oz — Hydrates, Defines Curls & Heat Protects

KÉRASTASE Curl Manifesto Crème de Jour Fondamentale is a lightweight leave-in cream that hydrates, defines and tames frizz for wavy, curly, very curly and coily hair while adding heat protection and shine.

Designed to be applied to towel-dried hair, this daily leave-in treatment blends Manuka honey and a ceramide-based complex to restore moisture, strengthen the curl structure and improve manageability without weighing strands down. The formula targets common curly-hair concerns—frizz, dryness, breakage and unclear pattern formation—so curls look more defined and feel softer after styling. It also offers thermal defense for styling with blow dryers, diffusers and tools up to 450° F.

How will this cream change my curl pattern and definition?

The cream helps form and emphasize natural curl shape by providing moisture and light slip that encourages pattern creation when you rake and scrunch. With repeated use as part of the Curl Manifesto range, clinical-style results show improved definition and conditioning.

• Adds hydration to encourage curl clumping and shape.
• Lightweight texture prevents flattening or residue buildup.
• Improves definition—72% more definition reported with regimen use.

Will it control frizz and protect from heat during styling?

Yes — the formula delivers all-day frizz control and shields strands from thermal damage during heat styling. It reduces visible frizz immediately for up to 24 hours while providing heat protection rated up to 450° F.

• Instant frizz reduction and humidity resistance.
• Heat protection suitable for blow dryers, diffusers, and hot tools.
• Maintains shine and softness even after styling.

How should I use this leave-in for best results?

Apply to clean, wet, towel-dried hair and work the product from roots to ends; do not rinse. Rake through sections and scrunch to form curl patterns, then let air dry or diffuse for enhanced shape and volume.

• Use a generous amount on wet, towel-dried hair for even coverage.
• Rake and scrunch to define curls—leave product in place.
• Works best when paired with other Curl Manifesto products for full benefits.

What key ingredients make it effective?

The formula combines hydrating Manuka honey with a ceramide complex that helps cement and strengthen the hair fiber. These actives balance moisture and structural support, improving detangling, conditioning and resistance to breakage over time.

• Manuka honey: attracts and locks in moisture for softer curls.
• Ceramide complex: reinforces curl structure and reduces breakage.
• Light, non-greasy base: preserves volume and natural bounce.

Who is this for: KÉRASTASE Curl Manifesto Crème de Jour Fondamentale is formulated for anyone with wavy, curly, very curly or coily hair seeking daily moisture, easier styling, stronger curls and effective frizz control without heaviness. It’s a good pick if you use heat tools sometimes, want cleaner curl definition, or need a leave-in that works alongside a full curl-care regimen.
