KÉRASTASE Repairing Gloss Oil for Damaged Hair — 30 ml, Lightweight Heat Protection & Shine

KÉRASTASE Première Repairing Gloss Oil is a leave-in treatment oil that repairs visible damage, boosts shine and shields hair from heat up to 450°F.

This lightweight gloss oil is designed for damaged or stressed hair that needs strengthening, smoothing and instant luminosity. Formulated with citric acid to clarify mineral buildup and glycine to support keratin bonds, the serum targets split ends and dullness while adding slip for easier styling. Use on damp or dry hair as a finishing step before blow-drying or as a touch-up for added sheen throughout the day.

How does this oil reduce split ends and visible damage?

The oil pairs citric acid and glycine to address surface buildup and reinforce weakened keratin links, which helps hair look less frayed at the ends. Its conditioning agents smooth the cuticle, improving the appearance of damaged strands.

• Citric acid helps remove mineral and product residue for a cleaner feel.
• Glycine supports internal keratin chain reconnection to reduce breakage.
• Leaves ends smoother and less prone to visible splitting.

Will it protect my hair from heat styling?

Yes — the formula offers heat protection up to 450°F, allowing safer use with blow-dryers and heated tools when applied appropriately. It also adds conditioning that reduces friction during styling.

• Apply 1–2 pipettes before heat styling for thermal defense.
• Lightweight texture avoids weighing down fine hair.
• Helps maintain shine and manageability after hot-tool use.

How should I use it for best results on damp or dry hair?

Dispense one to two pipettes and distribute through lengths and ends; leave in and style as usual. On damp hair, it primes for blow-drying; on dry hair, it smooths frizz and enhances shine as a finishing touch.

• Damp hair: apply before blow-drying to protect and detangle.
• Dry hair: use sparingly to tame flyaways and boost gloss.
• Can be combined with other styling products without heavy buildup.

What visible benefits can I expect and how quickly?

Users notice enhanced shine and smoother-looking hair immediately after application; strengthened feel and reduced breakage appear with repeated use. The brand cites up to 4x more shine and 99% stronger hair vs. specific baselines under tested conditions.*

• Instant increase in surface gloss and softness.
• Progressive improvement in resilience with regular use.
• Protects hair during heat styling sessions to maintain results.
