Best Kérastase Oil for Hair (By Hair Need)

If you want salon-level shine without heaviness, Kérastase’s oils are the gold standard. The brand blends lightweight silicones with nourishing oils (like marula, camellia, argan) to smooth frizz, add gloss, protect from heat, and keep ends from drying out—without that greasy “film.”

Below are the four standout Kérastase oils, matched to common hair needs: all-around shine, thick/frizzy control, curl nourishment (including scalp), and post-bleach repair. Each pick includes what it’s best for, how it actually feels and performs, and simple “use it like this” tips so you get results on day one.

Ratings reflect a summary of owner feedback and stylist commentary.

Deep Dives

1) Kérastase Elixir Ultime L’Huile Originale — Best Overall Shine + Softness

Rating: 4.8/5
What it is: A light, silky oil-serum that doubles as a heat protectant and finishing gloss.
Why it’s great: Adds instant polish and slip without flattening fine strands or leaving a residue on thicker hair. Works pre-blow-dry to speed styling and post-style to smooth flyaways.
Who it’s for: Anyone who wants healthier-looking ends and a reflective finish; safe for color.
How to use: 1–2 pumps for fine/medium hair, 2–4 for thick. Apply mid-lengths to ends before heat, and a half pump after styling to seal.
Pros

• Versatile (pre-style, finish, next-day refresher)
• Noticeable shine/gloss with soft touch
• Doesn’t weigh down most fine hair
  Keep in mind
• Use a tiny amount near roots to avoid flattening lift

2) Kérastase Discipline Oléo-Relax Advanced Oil — Best for Thick/Frizzy Hair & Humidity

Rating: 4.7/5
What it is: A smoothing oil designed to keep volume and frizz in check, even in damp climates.
Why it’s great: Softens coarse cuticles, reduces “triangle” puff, and helps maintain sleek blowouts longer.
Who it’s for: Medium-thick to coarse hair, high-porosity, or anyone battling humidity frizz.
How to use: 2–3 pumps on towel-dried hair before blow-drying; add a pea-size half pump as a finish if needed.
Pros

• Strong frizz and humidity control
• Sleek finish without crunch or stiffness
  Keep in mind
• Can feel rich for very fine, short hair (use sparingly or pick L’Huile Originale)

3) Kérastase Curl Manifesto Huile Sublime Repair — Best for Curls/Coils & Scalp Comfort

Rating: 4.6/5
What it is: A multi-use oil for waves, curls, and coils that also plays nicely with scalp massage.
Why it’s great: Adds slip and softness, reduces frizz halo, and layers well with curl creams/gels. Great for SOTC (scrunch-out-the-crunch).
Who it’s for: 2A–4C curls/coils; protective styles needing sheen at ends; dry/itchy scalp.
How to use:

• Wash day: Smooth 1–3 pumps over damp curls after cream/gel, then diffuse or air-dry.
• Finish: A half pump to scrunch out the cast and add shine.
• Scalp: A few drops to fingertips, massage 2–3 min pre-wash.
  Pros
• Curl-safe, flexible uses (lengths + scalp)
• Helps reduce frizz without killing definition
  Keep in mind
• As a scalp pre-treat, rinse thoroughly to avoid residue

4) Kérastase Blond Absolu Huile Cicaextreme — Best for Bleached, Fragile Hair

Rating: 4.7/5
What it is: A protective oil tailored to sensitized, lightened hair to help reduce snap and dryness.
Why it’s great: Cushions the hair fiber during heat styling and adds luminosity so blonde/gray looks glossy, not dull.
Who it’s for: Bleached, highlighted, or very light hair that feels rough on the ends.
How to use: 1–2 pumps on damp mid-lengths/ends pre-blow-dry; add a micro-pump after styling to seal.
Pros

• Improves “slip” on fragile ends
• Shine without brassiness
  Keep in mind
• Pair with a bond-care or strengthening routine for breakage-prone hair

How to Choose the Right Kérastase Oil

• Hair density & porosity: Fine, low-porosity hair usually prefers Elixir Ultime L’Huile Originale (or very tiny amounts of other oils). High-porosity or coarse hair can handle Oléo-Relax.
• Texture & goals: Curls/coils benefit from Huile Sublime Repair to layer into a curl routine. Bleached hair gets extra cushioning from Huile Cicaextreme.
• Climate: If humidity undoes your blowouts, prioritize Oléo-Relax.
• Styling routine: If you heat style often, all four provide heat protection—apply to damp hair first, then finish with a micro-pump on dry hair for polish.

Application Tips (No Grease, Just Gloss)

• Start with ½–1 pump, emulsify in palms, and apply mid-lengths to ends. Add more only if needed.
• For root flyaways, tap whatever’s left on your hands over the part—don’t pump more.
• For next-day refresh, warm a tiny dab between hands and “glass” over the surface and ends.
