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.
Synthetic hold polymers, the firmest kind of hold.
Film formers with little to soften them, so expect a cast to scrunch out.
Water-first and light: unlikely to flatten fine hair.
No absorbent powders or starches.
No oils or butters in the list.
No fast-drying alcohol in the list.
Nothing here needs a detergent wash to remove.
Fragrance is listed; it sits below the working ingredients.

Full ingredient list (17)
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
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.

Polyquaternium-55
General function
A conditioning hold polymer used where flexibility and shine matter more than stiffness.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitCurls or waves needing flexible holdCationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
May suitFrizz-prone, damaged, or high-friction hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Cocamidopropyl Hydroxysultaine
General function
A mild co-cleanser that keeps foam stable in hard water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May suitVery dry or highly damaged hairOne of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

Aloe Barbadensis Leaf Juice
· Aloe Barbadensis Leaf
General function
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitCurls or waves needing flexible holdGums thicken and set soft, which gives definition that bends rather than a rigid cast.
May suitFine or easily flattened hairHydration with no oil attached, so it adds very little weight even high on a list.
May suitVery dry or highly damaged hairAloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.

PVP
General function
A classic hairspray polymer. It gives firm hold but attracts moisture, so humidity can soften the set.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay 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.
May not suitClimate-sensitive or frizz-prone hairThe film takes up water from the air. The patent work that produced the VP/VA copolymers describes a PVP film turning sticky after time in a humid atmosphere, and being dependable only where humidity is low — so hold and feel both move with the weather.

Tocopheryl Acetate
General function
A stable form of vitamin E used to keep the oils in a formula from oxidising. It is used at fractions of a percent.
Estimated lower-concentration zonePubChemIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
- antioxidant
- vitamin

Citric Acid
General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.
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 TrichologyMay suitBuild-up-sensitive routinesHolds hard-water minerals in solution so they rinse away instead of depositing on the hair.
May suitFrizz-prone, damaged, or high-friction hairThe acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.
May suitGray, silver, or brass-prone hairWhere a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.
- pH adjuster
- hard-water chelator

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.

Ethylhexylglycerin

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.

Isostearamidopropyl Morpholine Lactate
General function
A cationic conditioning agent: an amidoamine salt that attaches to the negatively charged hair surface to cut combing friction and static. Milder and less substantive than a quaternary ammonium conditioner.
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 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.
May suitVery dry or highly damaged hairThe class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

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 2 listings we don’t count, from grey-market or unverified sellers.
How we work this out
- 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 $10.99 is the price we have observed for the 7 oz. We need three stores before we call a price commonly seen.
- Good value under $13 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.88/oz; at 7 oz that is $13. Under that line you are paying less than most of them.
- About $15 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 7 oz.
Formula
A complete formula at an ordinary price: mid-range per ounce among mousses, with the working systems in place.
How the score is counted
- 2 products that do the same job cost less per ounce
- Costs less per ounce than 63% of the 201 mousses we’ve priced
- Covers 6 of the 6 things a mouss should do
- Reviewers mention 2 things they like about how it performs
- A hold systemThe polymer, gum, or wax that holds the shape.3 pts
- Softeners alongside the holdWhat keeps a film flexible instead of brittle.2 pts
- No drying alcohol in the first threeFast drying without leading on alcohol.2 pts
- A humectantBinds water into the hair.1 pt
- A humidity claim with a mechanismThe claim has a film former or silicone behind it.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.

Final decision
Should you buy it?
A solid pick for the hair it suitsPeople who want maximum slip, for real detangling slip and a curly-method-compatible formula
Worth skipping for anyone sensitive to fragrance, anyone who will not scrunch out a cast, or very dry or very humid climates

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.
- 4 sources consulted for this product (1 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-31.
- Ingredient references are linked for 4 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 2026-10-07.
