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.

Hold (as stated) Strong

A strong hold, as stated by the brand.

Hold system Synthetic polymer

Synthetic hold polymers, the firmest kind of hold.

Cast risk Likely

Film formers with little to soften them, so expect a cast to scrunch out.

Weight on the hair Light

Water-first and light: unlikely to flatten fine hair.

Humidity resistance Claimed

The brand claims humidity resistance; the ingredient list cannot confirm it.

Oil absorption None

No absorbent powders or starches.

Oils and butters None

No oils or butters in the list.

Fast-drying alcohol High in the list

Fast-drying alcohol in the first three ingredients.

Needs detergent to remove Rinses with water

The silicones here are the water-soluble kind.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Ingredients that matter

The ingredients that change a decision

The workhorse ingredients, plus anything lower down that changes a decision. The chips name what an ingredient does. They are not safety scores, and no ingredient here is rated good or bad on its own.

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.

1 Alcohol Denat. · ALCOHOL DENAT

General function
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.

Role in this product type
In hairspray, denatured alcohol acts as a fast-evaporating solvent that carries the styling polymers and helps distribute them in a fine spray. As it evaporates, the polymers remain on the hair to form the hold film.

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

May suitFine or easily flattened hair
May suit hair that needs a fast-drying, lightweight spray base rather than an oil- or wax-led finish.

May not suitDry, coarse, or high-porosity hair
Porous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.

DependsVery dry or highly damaged hair
Consider if hair is very dry or highly damaged: when alcohol is this prominent, the fast-evaporating base may leave the hair feeling drier.

2 Hydrofluorocarbon 152a

General function
A non-flammable aerosol propellant used in dry shampoos and finishing sprays.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
PubChem
- propellant
3 Water · AQUA/WATER/EAU

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 ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
- solvent
4 Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer

General function
A firm hold polymer used in hairsprays and gels. It holds well in humidity and brushes out.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitClimate-sensitive or frizz-prone hair
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

May suitMaximum-hold styling
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

DependsBuild-up-sensitive routines
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
- film former
- polymer
▾Below about here, the order stops meaning much. These are usually used at 1% or less.
5 Aminomethyl Propanol

General function
A base used in trace amounts to neutralise acidic hold polymers so they thicken and set properly.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

DependsFrizz-prone, damaged, or high-friction hair
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

PubChem
- pH adjuster
6 Ammonium benzoate

General function
The ammonium salt of benzoic acid, used to protect a product from microbial spoilage.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
- preservative
- salt
7 PEG-8 Dimethicone

General function
A water-soluble silicone that smooths without the build-up concern of standard silicones.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
The PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.

May suitClimate-sensitive or frizz-prone hair
A 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 hair
Delivers the slip and surface smoothing of a silicone without needing a detergent wash to remove it afterwards.
- emulsifier
- silicone
- water-soluble silicone
8 Acetamide MEA

General function
A humectant that also improves slip, used in conditioners and styling creams.

Estimated lower-concentration zone
It 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 hair
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

May suitVery dry or highly damaged hair
Humectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.

DependsClimate-sensitive or frizz-prone hair
A 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.

PubChem
- humectant
- conditioning agent
9 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 zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May not suitFragrance-sensitive routines
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
- fragrance
- declared fragrance
10 GLYCERETH-7 TRIACETATE
11 Panthenol

General function
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFine or easily flattened hair
It hydrates without adding oil or a film, which is the combination fine hair usually needs.

May suitFrizz-prone, damaged, or high-friction hair
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

May suitVery dry or highly damaged hair
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

PubChem
- humectant
- conditioning agent
- vitamin
12 Triethyl Citrate

General function
A citrate ester used to stabilise fragrance and support the preservative system.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

DependsFrizz-prone, damaged, or high-friction hair

13 Mentha Arvensis Leaf Oil

General function
Cornmint oil, used for a cooling sensation and mint scent.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May not suitFragrance-sensitive routines

14 Benzyl Salicylate

General function
A soft floral fragrance component listed separately as a recognised allergen.

General function
Peppermint essential oil, used for scent and the cooling feeling on the scalp.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May not suitFragrance-sensitive routines
Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.

17 Alpha-Isomethyl Ionone

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

May suitBuild-up-sensitive routines
Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

May suitFrizz-prone, damaged, or high-friction hair
The 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 hair
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

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

10.5 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 10.5 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 $21 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.96/oz; at 10.5 oz that is $21. Under that line you are paying less than most of them.
About $29 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 10.5 oz.

Claims check

What the brand says, and what the formula shows

Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

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.
6 sources consulted for this product (2 manufacturer or regulatory, 2 retailer, 2 editorial), last checked 2026-09-13.
Ingredient references are linked for 12 of 17 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.
