Boo’s Take


This is not some cheap shiny nonsense. It is a luxury finishing oil-serum for people who want polished, glossy, expensive-looking hair fast. The real pull is the combo of shine, anti-frizz control, softness, and heat protection in a travel-size format.

If your hair gets puffy, dull, or rough-looking after styling, this product makes sense. Kérastase positions it as a lightweight, non-greasy oil-in-serum that gives up to 96 hours of anti-frizz action, makes hair 2x shinier after one application, and protects from heat up to 230°C. The Amazon.in listing also presents it as a 30 ml travel-size option for on-the-go use.

Why It’s Worth The Hype

  • The shine claim is the main event. This is built for glossy, smoother-looking hair, not just basic oiling. The brand’s headline claim is 2x shinier hair after one application.

  • It actually targets frizz for longer than most styling oils. Kérastase claims up to 96 hours of anti-frizz action, including in humidity, which is the kind of benefit people actually care about in real life.

  • The ingredient story is luxe and deliberate. The formula is described as being infused with Wild Camellia, French Camellia, and Marula oil; the official page also mentions Argan oil.

  • It is more flexible than a basic serum. The official directions say it can be used pre-cleanse, pre-blow dry, as a finishing step, or for touch-ups.

Best for

This is best for frizzy, dull, rough, or hard-to-manage hair that needs shine and softness without a greasy finish. It also makes sense for people who heat-style often and want one product that smooths, protects, and finishes at the same time. Kérastase presents it for frizz control and says it works as a heat protectant up to 230°C.

What You Can Realistically Expect

Expect smoother lengths, less visible frizz, softer texture, and a more reflective finish. Expect your hair to look more expensive, not magically repaired from hell. This is a styling-support product with nourishment benefits, not a full damage-reversal miracle. The official page describes it as lightweight and non-greasy, which matters because a shine product that weighs hair down is useless.

How to use

Directions to use : Prep hair / take 1–2 pumps into palms → apply evenly through lengths, focusing on mid-lengths and ends → use on damp hair before blow-drying or on dry hair as a finishing serum / touch-up.
Amount : 1–2 pumps, adjusted to hair thickness
Frequency : Daily or as needed for styling / touch-ups. This is an inference from the official multi-use directions rather than a stated fixed schedule.
Pairs well with : Blow-drying, heat styling, finishing, and anti-frizz touch-ups.

Skip if

  • You want a heavy overnight oil treatment instead of a lightweight glossing serum.

  • You hate fragranced luxury haircare and only want bare-bones functional formulas.

  • Your hair gets limp easily and you always overapply oils. One product cannot save you from bad technique.

  • You want deep repair on a budget. This is premium shine care, not cheap utility.

Boo Approved ✅ 73%

Verdict: Luxury shine serum with strong finish appeal, but the score is held back by price. Best for someone who wants glossy, smoother, less-frizzy hair and does not mind paying premium for a polished hair look.

  • Results — 80%
    The strongest payoff here is smoother, shinier, more polished hair with better frizz control. The brand positions it around 2X shine and 96-hour anti-frizz action, and the product is clearly built as a finish-and-smoothing serum rather than a deep repair miracle.

  • Value for Money — 58%
    This is the drag. At about ₹2,700 for 30ml on Amazon India, it sits firmly in luxury territory, so the price-to-payoff logic gets harder unless you really care about finish, shine, and frizz control.

  • Formula / Sensitivity — 72%
    The oil blend is positioned as nourishing and softening, with camellia, marula, and argan oils in the formula story. That supports a solid comfort score, but I would not push it higher without broader sensitive-scalp or irritation-specific user evidence.

  • Texture / Layering — 79%
    This category scores well because the whole point is a lightweight oil-in-serum finish that smooths without making hair look flat or greasy when used properly.

  • Routine Fit — 76%
    Easy to slot into a routine because it works as a finishing or anti-frizz step and is travel-size, which helps real-life usability.
