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.
Shine system
Silicone serum
A silicone or oil blend does the shine work here.
Weight on the hair
Rich
Heavy butters and waxes in the first eight ingredients.
Oils and butters

What the list leaves out, and what it carriesThe list carries no sulfates or drying alcohols. No protein: a moisture formula, not a repair one. Fragrance is on the label. Heavier butters sit in the working part of the list.
Full ingredient list (18)
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.
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.
- solvent
- emollient
-
2
Dimethicone
General function
The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.
Role in this product typeIn a finishing oil, dimethicone spreads as a smooth, low-friction layer over the hair surface. It improves slip, reduces flyaways, and creates a glossier finish.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
DowMay suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFrizz-prone, damaged, or high-friction hairMay suit frizz-prone, damaged, or high-friction hair that benefits from surface smoothing and added slip.
DependsBuild-up-sensitive routinesConsider cleansing habits: dimethicone is not water-soluble, so repeated use may leave more deposited film than a low-detergent routine removes.

- emollient
- conditioning agent

Coco-Caprylate/Caprate
· COCO-CAPRYLATE
General function
A plant-derived light ester used where a silicone-free but silky feel is wanted.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.
May suitFrizz-prone, damaged, or high-friction hairSpreads thin and lowers friction between strands without the heaviness of a fixed oil.
- light ester
- emollient

4
Phenyl Trimethicone
General function
A high-refractive silicone used specifically for visible shine in serums and finishing oils.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFrizz-prone, damaged, or high-friction hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
May not suitBuild-up-sensitive routinesDimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
- silicone
- emollient

Bis-Carboxydecyl Dimethicone
General function
A silicone polymer used as a film former and conditioning agent.

Salvia Hispanica Seed Extract

Chia seed extract, used at low levels for moisture claims.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- botanical extract
-
7
Zea Mays (Corn) Oil
General function
The oil pressed from Corn (Zea Mays). How much weight a plant oil leaves depends on the hair it lands on; coarse hair tends to take more of it than fine hair.

Beta-Carotene
General function
A plant pigment used as an antioxidant; it also tints the product orange.

May suitGray, silver, or brass-prone hairA violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.
- antioxidant
- colourant

Fragrance
General function
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

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 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 $5.99 is the price we have observed for the 1 oz. We need three stores before we call a price commonly seen.
- Good value under $8 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $7.70/oz; at 1 oz that is $8. Under that line you are paying less than most of them.
- About $11 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1 oz.

A complete formula at an ordinary price: mid-range per ounce among hair oils, with the working systems in place.
How the score is counted
- 2 products that do the same job cost less per ounce
- Costs less per ounce than 58% of the 270 hair oils we’ve priced

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
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

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.
- 1 source consulted for this product (1 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-10-03.
- 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 2026-10-03.
