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.
A silicone or oil blend does the shine work here.
Middle of the range: noticeable on fine hair, light on coarse hair.
No oils or butters in the list.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No fast-drying alcohol in the list.
Fragrance is listed; it sits below the working ingredients.

Full ingredient list (12)
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
Cyclopentasiloxane
General function
A light, fast-evaporating silicone that spreads other ingredients then leaves. It gives serums their weightless glide.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitBuild-up-sensitive routinesIt leaves the hair by evaporating rather than by being washed off, so it is not part of what accumulates.
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 suitFine or easily flattened hairA cyclic silicone evaporates after it has spread the formula, so it carries the other ingredients without leaving weight behind.
- silicone
- 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.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
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.

Dimethiconol
General function
A high-shine silicone often paired with dimethicone for a smoother, glossier finish.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay 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.

Isododecane
General function
A fast-evaporating carrier that lets oils and polymers spread thinly, then leaves nothing behind.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

- emollient

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.

Hydrolyzed Vegetable Protein PG-Propyl Silanetriol
General function
A plant protein modified to bind more firmly to hair than a plain hydrolysed protein. Used for strength and body claims.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFrizz-prone, damaged, or high-friction hairFilling 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 stylingFilm 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 hairHydrolysed 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.

Caviar Extract
General function
A fish-roe extract used at trace levels for luxury positioning. It is animal-derived.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May not suitProtein-sensitive hairA large surface-depositing protein. If protein reliably makes your hair feel rigid, this is the form most likely to do it.
DependsVery dry or highly damaged hairUnhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.

- protein

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.

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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
International Journal of Cosmetic ScienceMay suitFrizz-prone, damaged, or high-friction hairFilling 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 stylingFilm 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 hairSize decides where it goes. In fibre testing, fractions around 221 and 2,577 Da reached the cortex while a 75,440 Da fraction stayed on the surface. A label prints the name, never the size, so a protein line is a claim about the ingredient rather than about the depth.

Fragrance
· Fragrance (Parfum)
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 zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

$38.001.7 oz · $22.35/ozAug 27Lowest per oz
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
- 1.7 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 $38 is the price we have observed for the 1.7 oz. We need three stores before we call a price commonly seen.
- Good value under $4 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.58/oz; at 1.7 oz that is $4. Under that line you are paying less than most of them.
- About $8 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1.7 oz.
Formula
The formula carries what a serum is built around, and 7 products we score as close matches cost at least a quarter less per ounce. The difference is the label, not the formula.
How the score is counted
- 7 products we score as doing the same job cost less per ounce
- Costs more per ounce than 91% of the 136 serums we’ve priced
- Covers 5 of the 6 things a serum should do
- Reviewers mention 3 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
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.
- 3 sources consulted for this product (1 manufacturer or regulatory, 1 retailer, 1 editorial), last checked 2026-09-04.
- Ingredient references are linked for 4 of 10 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.
