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.
Heavy butters and waxes in the first eight ingredients.
Oils sit high in the list — a softening, coating formula.
The brand claims humidity resistance; the ingredient list cannot confirm it.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No fast-drying alcohol in the list.
Fragrance sits in the first eight ingredients — a larger share of the formula.

Full ingredient list (15)
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
Cyclopentasiloxane
· Cyclomethicone
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.

- emollient

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.

Phenyl Trimethicone
General function
A high-refractive silicone used specifically for visible shine in serums and finishing oils.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.

Bis-Vinyl Dimethicone
General function
A silicone that cross-links into a network, leaving a smoothing film with more staying power than plain dimethicone.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- silicone
- film former
-
5
Diphenyl Dimethicone
General function
A silicone. Silicones coat the strand for slip, shine and frizz control; unless the name carries PEG or PPG, removing one takes a detergent rather than water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

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

Argania Spinosa Kernel Oil
· Argania Spinosa (Argan) Kernel Oil
General function
Argan oil. A medium-weight oil used for shine and softness on the outside of the strand.
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.
May suitDry, coarse, or high-porosity hairCoats 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 hairA thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

Hydrogenated Vegetable Glycerides Citrate
General function
A plant-fat emulsifier used to hold creams together without ethoxylation.

Lecithin
General function
A soy- or sunflower-derived lipid that helps conditioning ingredients spread evenly on the strand.
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.
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.

Squalene
General function
The unsaturated parent of squalane and a natural component of scalp sebum. It is less stable than squalane and oxidises faster.
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.

Propylene Glycol
General function
A small humectant and solvent that keeps formulas stable and helps active ingredients spread.
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.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it hydrates without contributing weight.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
DependsClimate-sensitive or frizz-prone hairA humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

$32.001.7 oz · $18.82/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 $32 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 $14 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $8.29/oz; at 1.7 oz that is $14. Under that line you are paying less than most of them.
- About $21 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1.7 oz.
Formula
Above the range for serums per ounce for a formula that 6 lower-priced products come close to on ingredients and attributes.
How the score is counted
- 6 products that do the same job cost less per ounce
- Costs more per ounce than 88% of the 77 serums we’ve priced
- No weightless carrier in the formula
- Reviewers mention 4 things they like about how it performs

- 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

- 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.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

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.
- 1 source consulted for this product (1 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-27.
- Ingredient references are linked for 3 of 9 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 2026-08-28.
