KÉRASTASE Nutritive Split Ends Hair Serum for Dry Hair — 1.7 fl oz, Ultra-Sealing Nourishing Leave-In Oil for Smoothness & Shine

KÉRASTASE Nutritive Split Ends Hair Serum is a lightweight leave-in oil that instantly smooths and seals split ends while deeply nourishing dry hair for shine and reduced breakage.

This ultra-sealing serum is formulated to target dehydrated ends: a concentrated blend of plant-based proteins and niacinamide helps restore moisture balance, reduce visible split ends, and protect against future damage. Designed for daily use on dry or towel-dried hair, the formula absorbs quickly without leaving heavy residue, delivering a soft, radiant finish. Use it as part of the Nutritive routine alongside a moisturizing shampoo, conditioner, and heat protectant for best results.

How does this serum improve the look of split ends?

The serum forms an ultra-sealing layer around frayed hair tips to smooth texture and reduce the appearance of splits. Over repeated use, the nourishing ingredients strengthen weakened fibers to lessen breakage and keep ends looking healthier.

• Seals and smooths split ends for an instantly neater finish
• Plant-based proteins reinforce hair structure at the ends
• Leaves a lightweight glossy sheen without weighing hair down

When and how should I apply the Nutritive Split Ends Serum?

Apply a few drops to dry or towel-dried hair, concentrating on mid-lengths and ends where damage is most visible. Five small doses are recommended for full application; gently massage in and do not rinse—style as usual.

• Use on towel-dried hair for better absorption or on dry hair to tame flyaways
• Focus on mid-lengths to ends; avoid the roots to prevent greasiness
• Do not rinse out; incorporate into morning or pre-styling routine

What active ingredients are in the formula and what do they do?

The serum combines plant-based proteins with niacinamide and anti-dryness polymers to hydrate, strengthen, and create a protective film. These components work together to lock in moisture, improve elasticity, and reduce surface roughness for smoother, more resilient ends.

• Plant-based proteins: nourish and reinforce the hair fiber
• Niacinamide: helps retain moisture for lasting hydration
• Anti-dryness polymers: form an ultra-sealing layer on the hair tip

Will this serum suit my hair type and styling routine?

Nutritive Split Ends Serum is suitable for all hair types prone to dryness or end damage, from fine to thick textures. Because it’s lightweight, it can be paired with heat styling and other products—just avoid overapplication to keep hair from feeling heavy.

• Ideal for dry, brittle, chemically treated, or heat-styled ends
• Compatible with heat protectants and other leave-in treatments
• Use as part of a complete Nutritive regimen for optimum results

Who is this for? If you regularly experience split ends, dryness, or loss of shine—especially at mid-lengths and tips—this serum is formulated to deliver targeted nourishment and sealing action. It’s a practical addition for anyone wanting an easy, leave-in treatment to smooth ends, reduce visible splitting, and restore natural radiance without heavy buildup. Ideal for daily use and for those who style with heat or color their hair and need extra reinforcement at the tips.
