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.
Water-first and light: unlikely to flatten fine hair.
Conditioning agents sit high in the list, so this is a detangling formula.
Nothing here needs a detergent wash to remove.
Humectants in the working part of the formula.
No fast-drying alcohol in the list.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Full ingredient list (21)
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
· AQUA (WATER)
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
Guar Hydroxypropyltrimonium Chloride
General function
A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitCurls or waves needing flexible holdGums thicken and set soft, which gives definition that bends rather than a rigid cast.
May suitFrizz-prone, damaged, or high-friction hairCationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
May suitMaximum-hold stylingA styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.

- polymer
- gum

3
sodium laneth-40 maleate/styrene sulfonate 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.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitClimate-sensitive or frizz-prone hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
May suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
DependsBuild-up-sensitive routinesSome acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.

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.

Polysorbate 20
· POLYSORBATE-20
General function
Keeps fragrance and oils dissolved in a watery formula so it stays clear.

- solubilizer

Dehydroxanthan Gum
General function
A plant or fermented gum. Gums thicken a water-based formula and give it a slippery, cushioned feel; in a styler they also contribute soft hold.
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 suitCurls or waves needing flexible holdA polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
May suitFrizz-prone, damaged, or high-friction hairA soft film binds neighbouring strands together, which is most of what helps flyaways lie down.
May not suitMaximum-hold stylingGum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.

Polysorbate 80
General function
A solubiliser that dissolves fragrance and oils into water so the product stays clear.

- emulsifier
- solubilizer

Caprylhydroxamic Acid
· CAORYLHYDROXAMIC ACID
General function
A coconut-derived preservative booster that also binds trace metals.
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 suitBuild-up-sensitive routinesBinds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
May suitGray, silver, or brass-prone hairCopper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.

Caprylyl Glycol
General function
A gentle preservative helper that also holds a little moisture.
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 suitVery dry or highly damaged hairHumectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.
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.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
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.
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.

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

Silk Amino Acids
General function
Silk protein broken into amino acids, used for slip and shine rather than strength.
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 suitVery dry or highly damaged hairAmino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
DependsProtein-sensitive hairThe lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

$9.994 oz · $2.50/ozOct 7Lowest 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
- 4 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 $9.99 is the price we have observed for the 4 oz. We need three stores before we call a price commonly seen.
- Good value under $13 comes from the 5 products we score as doing the same job as this one. A quarter of them cost less than $3.17/oz; at 4 oz that is $13. 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 4 oz.
Formula
Nothing separates this from the middle of the range for heat protectants, on formula or on cost per ounce.
How the score is counted
- 1 products that do the same job cost less per ounce
- Costs less per ounce than 74% of the 295 heat protectants we’ve priced
- No stated heat claim in the formula

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 (0 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-10-07.
- Ingredient references are linked for 4 of 9 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 2026-10-08.
