What the formula actually does
Read from the label, not the marketing
Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.
Light esters or a volatile carrier: shine with little residue.
Oils are present, but low enough to be a finishing touch.
The brand claims humidity resistance; the ingredient list cannot confirm it.
Nothing here needs a detergent wash to remove.
Fragrance sits in the first eight ingredients — a larger share of the formula.

Full ingredient list (16)
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

1
Isododecane
General function
A fast-evaporating carrier that lets oils and polymers spread thinly, then leaves nothing behind.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

· Coco-Caprylate
General function
A plant-derived light ester used where a silicone-free but silky feel is wanted.

Polyglyceryl-3 Polyricinoleate
General function
A plant-derived polyglycerol ester. It emulsifies without ethoxylation, which is why it turns up in formulas positioned as PEG-free, and leaves a soft feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

6
Sorbitan Isostearate
General function
A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.

Squalane
General function
The fully hydrogenated form of squalene, now made from olive or sugarcane rather than shark liver. Hydrogenation is what makes it so slow to oxidise; it spreads very lightly and absorbs without a greasy film.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.
How we work this out
- 1.86 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
- Seen at $32 is the price we have observed for the 1.86 oz. We need three stores before we call a price commonly seen.
- Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
- About $19 is what hair oils typically cost at this size. Too few of the products that do the same job carry a price for us to draw a good-value line.
Formula
Above the range for hair oils per ounce for a complete formula, with no close, lower-priced match in our library.
How the score is counted
- Nothing in our library does the same job for less
- Costs more per ounce than 78% of the 169 hair oils we’ve priced
- Covers 5 of the 6 things a hair oil should do
- Reviewers mention 4 things they like about how it performs
- A shine systemThe silicone, oil, or ester that produces gloss.3 pts
- A weightless carrierDelivers the shine without leaving grease.2 pts
- Oils or butters in the working zoneSoftens the strand rather than just coating it.2 pts
- An antioxidantKeeps the oils in the bottle from going off.1 pt
- No drying alcohol in the first threeFast drying without leading on alcohol.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.

How this page was made
- Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per product.
- The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
- Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
- The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
- 7 sources consulted for this product (1 manufacturer or regulatory, 4 retailer, 2 editorial), last checked 2026-09-04.
- Ingredient references are linked for 4 of 12 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
- We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
- Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Formula readings: derivation v22. Record last updated 2026-09-04.
