Nutritive Hydrating Split Ends Serum
A leave-in serum designed to smooth, hydrate, and reduce the look of dry split ends without making hair feel overly coated.
A useful dry-hair finishing serum for people whose ends look rough, thirsty, or frayed between trims.
People whose ends look rough, dry, or frayed between salon visits — and who want something that makes a visible difference to the state of their ends without having to get a trim every 4 weeks.
Applied to dry or towel-dried ends at any point — can be used post-styling as a finishing step, or applied to dry hair mid-day when ends start looking rough or frayed. No rinse required.
People with dry, rough, or frequently fraying ends who want a daily maintenance serum that improves how their ends look and feel without waiting for a trim. Particularly useful for people growing out their hair.
If used in large amounts across the whole length of fine hair — the serum will make fine hair look flat and greasy. Fine hair should use the tiniest amount, focused only on the bottom inch of ends.
If hair feels coated or heavy, significantly reduce the amount used and focus only on the very tips of the hair.

About This Product
Kérastase Nutritive Hydrating Split Ends Serum is a targeted leave-in treatment from the Nutritive range — the line built around deep hydration for dry, thirsting hair. Split end serums sit within a specific product category: they cannot biologically repair a split strand (a split is a physical break in the hair fibre — only a trim can remove it), but they can temporarily bond and smooth the appearance of frayed, split ends to reduce roughness, tangling, and the visible frizz that dry ends create. The Nutritive serum focuses this end-care approach through a hydrating lens — rather than a heavy silicone coating, the formula prioritizes hydration-first conditioning of dry, frayed ends. This makes it particularly practical as a between-trim maintenance product: it keeps ends looking and feeling smoother and more hydrated while the user grows out or waits for their next haircut. The leave-in format means it can be applied to dry hair at any point in the day for immediate smoothing and hydration.
