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.
Middle of the range: noticeable on fine hair, light on coarse hair.
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.
No fast-drying alcohol in the list.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.
Ingredients that matter
The ingredients that change a decision
The workhorse ingredients, plus anything lower down that changes a decision. The chips name what an ingredient does. They are not safety scores, and no ingredient here is rated good or bad on its own.

Full ingredient list (16)
In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

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.

5
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.
- emulsifier
- emollient

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
- 2 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 $33 is the price we have observed for the 2 oz. We need three stores before we call a price commonly seen.
- Good value under $3 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.46/oz; at 2 oz that is $3. Under that line you are paying less than most of them.
- Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
- About $14 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 2 oz.
Formula
This is a complete hair oil formula. It is also above the range for hair oils per ounce, with 7 close matches selling for meaningfully less.
How the score is counted
- 7 products that do the same job cost less per ounce
- Costs more per ounce than 79% of the 270 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 measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.
Does the same job, for less

How this page was made
- Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one 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 general formulation guidance. They aren’t a verdict on the finished product or on you.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- 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 v23. Record last updated 2026-09-04.
