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.
Water-first and light: unlikely to flatten fine hair.
Oils are present, but low enough to be a finishing touch.
Nothing here needs a detergent wash to remove.
Contains fast-drying alcohol, which speeds drying but can leave hair feeling dry.
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

Full ingredient list (26)
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.

Water
· Water (aqua)
General function
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent

2
Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
May suitVery dry or highly damaged hairBinds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
DependsClimate-sensitive or frizz-prone hairWater moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.

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

Behentrimonium Chloride
General function
A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
International Journal of Cosmetic ScienceMay suitDry, coarse, or high-porosity hairElectrokinetic measurement puts the C22 quat ahead of the C16 ones for deposition: the longer chain adds van der Waals stabilisation on top of the charge binding. That extra deposit is what coarse hair usually needs to comb through.
May suitFrizz-prone, damaged, or high-friction hairA cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

- solubilizer
- emulsifier
-
6
Triticum Vulgare (Wheat) Protein
General function
Wheat protein, used for temporary strength and body. Whole protein sits on the surface rather than entering the strand.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitMaximum-hold stylingFilm 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 holdHow rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
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.

Hydroxypropylgluconamide
General function
A sugar-derived conditioning agent used in bond-repair positioned formulas for moisture and slip.
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 hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
May suitVery dry or highly damaged hairHumectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.

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.

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. and 3 listings we don’t count, from grey-market or unverified sellers.
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.
- Commonly seen is the middle half of current prices for the 1.7 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $14 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $7.96/oz; at 1.7 oz that is $14. Under that line you are paying less than most of them.
- About $17 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1.7 oz.
Formula
Nothing separates this from the middle of the range for serums, on formula or on cost per ounce.
How the score is counted
- Costs less per ounce than 65% of the 136 serums we’ve priced

Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.
Many reviewers say the serum feels lightweight, not greasy, and leaves hair soft and shiny.
Reviewers across hair typesSome reviewers say the ends felt dry or straw-like, especially when the serum went on dry hair.
Reviewers who applied it to dry hair or endsSome reviewers say they saw little change in their hair after using it for weeks.
Reviewers across hair typesScent divides reviewers, with many praising it and others finding it too floral or strong.
Reviewers sensitive to fragrance and those who prefer lighter scentsSome reviewers, especially those with finer hair, say it left hair greasy or weighed it down.

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, 2 retailer, 1 editorial), last checked 2026-10-31.
- Ingredient references are linked for 9 of 19 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 2026-08-28.
