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

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

This concentrated 30 ml oil from KÉRASTASE’s Première line targets weakened, dull, and split hair by combining citric acid and glycine to address surface buildup and help reconnect keratin links. It’s formulated to be used on damp or dry hair—one to two pipettes provide conditioning without weighing strands down. The formula helps reduce the appearance of split ends while adding gloss and protection during styling.

How does this oil repair damaged hair?

The Repairing Gloss Oil works on two visible signs of damage: surface dullness caused by mineral buildup and internal weakness where keratin bonds have been disrupted. Citric acid helps clarify and remove residue that mutes shine, while glycine supports the rebuilding of keratin connections to reduce breakage.

• Citric acid removes calcium buildup for a cleaner surface and brighter hair.
• Glycine helps reconnect broken keratin links to improve strand strength.
• Visibly reduces split ends and smooths hair cuticles for better light reflection.

Will it protect my hair during heat styling?

Yes—this formula offers heat protection up to 450°F, making it suitable for high-temperature tools. Apply before blow-drying or using straighteners/curling irons to add a protective layer and help prevent further thermal stress.

• Use on damp hair before blow-drying to shield cuticles from heat exposure.
• Apply to dry hair prior to flat-ironing or curling to reduce thermal wear.
• Light texture avoids greasiness while providing protective benefits.

How should I use the 30 ml oil for best results?

Dispense one or two pipettes depending on hair length and porosity; distribute through mid-lengths and ends, then leave in. For lighter hold and shine on fine hair use a single pipette; for coarse or longer hair use two. Style as usual—blow-dry or air-dry—this product is formulated as a leave-in finishing and protective oil.

• Apply 1–2 pipettes to damp hair for easier distribution and styling control.
• Apply to dry ends to tame frizz and add instant gloss without rinsing.
• Combine with heat styling for added protection and smoother finish.

What visible benefits can I expect and how quickly?

Results are visible immediately in shine and manageability; cumulative improvements in strength and the appearance of split ends appear with regular use. The brand reports up to 4× more shine compared with unwashed hair and a 99% increase in strength versus non-conditioning shampoo, reflecting comparative testing conditions.

• Instant: increased gloss and smoother feel after first application.
• Short-term: reduced appearance of split ends and better detangling.
• Ongoing: improved resistance to breakage with consistent use alongside other repairing products.

Who is this for: KÉRASTASE Première Repairing Gloss Oil is designed for people with damaged, dull, or split-prone hair who want a lightweight, leave-in treatment that adds shine and heat protection. It suits all hair types needing targeted repair—especially those who frequently heat-style, have product or mineral buildup, or want a finishing oil that doesn’t weigh hair down.
