KÉRASTASE Split Ends Hair Serum 1.7 fl oz — Lightweight Leave-In Oil to Seal & Smooth Dry Ends

KÉRASTASE Nutritive Split Ends Hair Serum is a lightweight leave-in oil that seals and nourishes dry ends to visibly reduce split ends while boosting smoothness and shine.

This ultra-sealing formula is designed for hair prone to dryness and visible split ends. Enriched with plant-based proteins and niacinamide, the serum delivers concentrated hydration to mid-lengths and ends, helps prevent future breakage, and leaves hair looking softer and more radiant without weighing it down. Use on towel-dried or dry hair as the last styling step for instant manageability and a polished finish.

How quickly will I notice fewer split ends?

Users often see an immediate improvement in the look and feel of their ends after the first application, with more measurable reduction in split ends after consistent use. The formula forms a protective, flexible seal around damaged tips that reduces visible splitting and minimizes further fraying.

• Instant smoothing effect on application
• Progressive reduction in visible split ends with repeated use
• Protective polymers help prevent new damage

How do I apply this serum for best results?

Apply a few drops to towel-dried or dry hair, concentrating on mid-lengths and ends. Gently massage until absorbed; do not rinse. For very dry ends, increase dosage slightly but avoid the roots to prevent greasiness.

• Recommended: five small doses per application for even coverage
• Work from mid-lengths to ends; avoid scalp
• Use as the final styling product for shine and seal

Will it weigh my hair down or leave residue?

The serum is crafted to be lightweight and fast-absorbing so it nourishes without heavy buildup. Because it targets ends and uses a refined oil base, you get added shine and softness without an oily feel on roots or visible residue.

• Light texture suitable for daily finishing
• Designed to absorb into damaged ends, not sit on the scalp
• Leaves a radiant, non-greasy finish

Can I use it alongside my other KÉRASTASE products?

Yes — the Nutritive Split Ends Serum integrates smoothly into a nourishing hair routine. For best outcomes, pair it with Nutritive shampoo, conditioner, and heat protectant; use the 8H Magic Night Serum at night for complementary overnight care.

• Works with Nutritive shampoo and conditioner for fuller effect
• Compatible with heat protectants and styling products
• Night serum complements daytime sealing for continuous care

Who this is for: ideal for anyone with dry, brittle, or chemically treated hair who wants to reduce visible split ends and add smoothness and shine. It suits all hair types that need targeted nutrition at the ends, especially those who heat-style or color-treat and want a lightweight, leave-in treatment to protect and refine their finish.
