Kérastase Nutritive Nutri-Supplement Split End Serum is a leave-in treatment that helps prevent split ends on dry, brittle hair. It nourishes deeply and seals the cuticle for smoother, healthier-looking ends — without any weight or grease.

Benefits
  • Helps prevent split ends — seals and protects fragile ends.
  • Deep nourishment — restores moisture to dry, brittle lengths.
  • Lightweight, non-greasy — absorbs fast and won't weigh hair down.
  • Frizz control — smooths the cuticle for a polished finish.
How to use
  1. On towel-dried hair, apply a small amount to mid-lengths and ends, avoiding the roots.
  2. Distribute evenly, and do not rinse.
  3. Add an extra touch to the driest ends as needed, then style.

Why our stylists rate it
From the Partners Hair team
Kérastase Nutritive Nutri-Supplement Split Ends Serum is a hydrating, ultra-sealing split-ends concentrate for dry hair. Part of the Kérastase Nutritive range. Lightweight vitamin-in-oil leave-in formula that nourishes, seals, and visibly reduces the appearance of split ends — a finishing-step concentrate used at the end of the Nutritive routine.

Best for: dry hair with visible split ends or rough ends; lengths that feel parched between haircuts; the finishing-care step in the Nutritive routine after Bain Satin/Bain Satin Riche + Lait Vital/Masquintense + Lotion Thermique/Nectar Thermique; daily polish for thirsty dry ends.
Less suited to: hard-water damage where decalcification is the priority (use Première Huile Gloss Réparatrice instead); blonde hair where colour care is priority (use Blond Absolu Cicagloss or Cicaextreme); damaged hair primarily needing structural repair (use Resistance Sérum Thérapiste); thick frizz-prone hair where smoothing is the priority (use Discipline L'Huile Oléo-Relax); fine, thinning hair where density is the goal (use Densifique range).

Key actives:
- Vitamin-in-oil blend — Kérastase's nourishing concentrate of plant-based proteins and vitamins
- Plant-based proteins (Hydrolyzed Wheat, Corn, and Soy) — deliver essential amino acids to thirsty fibre
- Niacinamide (Vitamin B3) — strengthens the fibre barrier; locks in moisture
- Anti-dryness polymers — ultra-sealing technology that wraps each strand
- Iconic Nutritive fragrance — violet leaves, ylang ylang, white jasmine

Benefits:
- 2x less split ends and instant smoothness (Kérastase test)
- +99% stronger hair (instrumental test, versus non-conditioning shampoo)
- +81% more shine (versus unwashed hair)
- Ultra-sealing finish — wraps and protects dry ends
- Helps prevent and reduce visible split ends
- Lightweight — no greasy residue or weight

How to use: Apply 5 drops to dry ends after the entire Nutritive routine. Can also be used on wet or dry hair as a leave-in treatment. Do not rinse. Style as desired. Pro tip: layer over Nectar Thermique or Lotion Thermique for added heat protection on damaged-feeling ends.

Format: 50ml leave-in oil concentrate.
