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 Volatile carrier

Light esters or a volatile carrier: shine with little residue.

Weight on the hair Medium

Middle of the range: noticeable on fine hair, light on coarse hair.

Oils and butters Present, lower down

Oils are present, but low enough to be a finishing touch.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Fragrance Prominent

Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

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 ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

PubChem
- solvent
- emollient
2 Isohexadecane

General function
A light, quickly evaporating carrier that spreads silicones and oils thinly, then leaves.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
- solvent
- emollient
3 C13-15 Alkane

General function
A plant-derived light alkane used as a clean-feeling replacement for silicone or mineral oil.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
- emollient
- solvent
4 Coconut Alkanes

General function
A coconut-derived light emollient used as a plant alternative to silicone.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

5 Coco-Caprylate/Caprate · Coco-Caprylate

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

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitFine or easily flattened hair
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

May suitFrizz-prone, damaged, or high-friction hair
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
- light ester
- emollient
6 Ethylene/Propylene/Styrene Copolymer

General function
A polymer used to thicken oils and hold a styling product's structure.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- film former
- polymer
- thickener
7 butylene/ethylene/styrene copolymer

General function
A synthetic film-forming polymer. Polymers of this kind dry to a continuous film on the hair, which is how a styling product holds a shape.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- film former
- polymer
▾Below about here, the order stops meaning much. These are usually used at 1% or less.
8 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.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May not suitFragrance-sensitive routines
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

9 Coco-Caprylate/Caprate

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

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFine or easily flattened hair

11 Crambe Abyssinica Seed Oil

General function
A light oil with very long fatty-acid chains, used as a plant alternative to silicone shine.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitDry, coarse, or high-porosity hair
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

May suitFrizz-prone, damaged, or high-friction hair
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
- oil
- emollient
12 Water
- solvent
13 Tocopherol
- antioxidant
- vitamin
14 Hydrolyzed Silk

General function
A light protein used for slip and shine rather than strength.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFrizz-prone, damaged, or high-friction hair
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

May suitVery dry or highly damaged hair
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
- film former
- protein
- hydrolysed protein
15 Helianthus Annuus Seed
16 Keratin

General function
The protein hair is made of. On the outside of the strand it fills gaps and firms up the feel for a few washes.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

DependsVery dry or highly damaged hair
Unhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.
- protein
17 Hydrolyzed Keratin

General function
Fragments of the same protein hair is made of. They fill gaps on damaged strands and make hair feel firmer for a few washes.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFrizz-prone, damaged, or high-friction hair
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

DependsCurls or waves needing flexible hold
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.

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

1.69 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 $12.23 is the price we have observed for the 1.69 oz. We need three stores before we call a price commonly seen.

We do not have enough serums with a computable price per ounce to say where this one sits. The formula itself carries the systems a serum is built around.

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.

Should you buy it?

Depends on your hair: see who it suits

Best user

Silicone-free routines, looking for a silicone-free formula and a product that will not force a clarifying wash

Biggest tradeoff

Less suited to anyone sensitive to fragrance or vegan and cruelty-free shopping

Best alternative if not

Nothing in our library matches it closely at a lower price.

We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.

Claims check

What the brand says, and what the formula shows

Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

How to read this

We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.

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.
3 sources consulted for this product (0 manufacturer or regulatory, 0 retailer, 3 editorial), last checked 2026-09-15.
Ingredient references are linked for 2 of 11 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 2026-09-16.
