KÉRASTASE Premiere Repairing Gloss Oil for Damaged Hair — Heat Protects to 450°F, Lightweight Shine

KÉRASTASE Premiere Repairing Gloss Oil is a leave-in repairing oil that strengthens damaged hair, protects against heat up to 450°F, and amplifies shine while reducing the look of split ends.

This lightweight, luxurious oil uses a targeted formula to address signs of damage and dullness without weighing hair down. Enriched with citric acid to lift mineral buildup and glycine to help reconnect weakened keratin links, the product is designed for routine use on damp or dry hair before styling. It’s part of the KÉRASTASE Premiere line, built for a dual-action approach to repair: improving hair’s internal resilience while restoring a glossy finish externally.

How does this oil protect hair during heat styling?

The formula forms a protective layer that helps shield strands from high temperatures, allowing safer blow-drying and hot-tool styling up to 450°F. It’s intended as a leave-in step used prior to heat exposure to reduce further surface damage.

• Heat protection rated up to 450°F for styling tools.
• Lightweight texture that won’t make hair greasy before styling.
• Suitable for use on damp hair before blow-drying or on dry hair before straightening or curling.

In what ways does it repair or strengthen damaged hair?

The oil combines citric acid and glycine to address both surface buildup and internal fiber weakness. Citric acid helps remove calcium and mineral deposits that dull hair, while glycine supports reconnection of broken keratin links to reduce breakage and improve resilience.

• Visibly reduces the appearance of split ends.
• Formulation targets mineral buildup and fiber reconnection.
• Reported to make hair 99% stronger versus non-conditioning shampoo.*

How does it improve shine and manageability?

The oil leaves a glossy sheen that reflects light and smooths the hair surface, giving an immediate polished look. Its slip-enhancing texture also aids detangling and makes styling easier, delivering four times more shine compared with unwashed hair according to the formula’s comparison.

• Delivers up to 4x more shine versus unwashed hair.
• Smooths fiber surface for easier comb-through and styling.
• Light finish suitable for multiple hair textures without heaviness.

How should I use the oil in my routine?

Use one to two pipettes on damp hair before drying or on dry hair prior to heat styling. It’s a leave-in product—work through mid-lengths to ends, then blow-dry or style as usual. Adjust the amount depending on hair thickness and porosity to avoid excess shine.

• Apply 1–2 pipettes to damp or dry hair; leave-in.
• Concentrate on mid-lengths and ends where damage is visible.
• Follow with blow-drying or hot tools up to 450°F if needed.

Who is this for: KÉRASTASE Premiere Repairing Gloss Oil suits anyone experiencing dryness, dullness, split ends or breakage from chemical or heat stress who wants a non-greasy, leave-in treatment. It’s useful for fine to thicker hair types that need heat protection, added shine, and a formula that targets mineral buildup and weakened keratin fibers.
