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 system
Synthetic polymer
Synthetic hold polymers, the firmest kind of hold.
Cast risk

Full ingredient list (22)
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.
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 typeIn 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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Cosmetic Ingredient ReviewMay suitFine or easily flattened hairMay 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 hairPorous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
DependsVery dry or highly damaged hairConsider if hair is very dry or highly damaged: when alcohol is this prominent, the fast-evaporating base may leave the hair feeling drier.

Water
· Water (Aqua) (Eau)

Polyurethane-14
General function
A flexible hold polymer that bends rather than cracks, used for touchable styling.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.
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.

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.

Ppg-12 Dimethicone
General function
A silicone made water-soluble by ethoxylation. It smooths and adds slip, and rinses out with water rather than needing a detergent.
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 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.

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
- 3.38 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 $23 is the price we have observed for the 3.38 oz. We need three stores before we call a price commonly seen.
- Good value under $3 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.96/oz; at 3.38 oz that is $3. Under that line you are paying less than most of them.
- About $7 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 3.38 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.

Reviewers
What people report
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.
Reviewers like a light, flexible hold that keeps a style in place with movement, never feels tacky or crunchy and leaves hair soft and brushable.
mostly fine-haired reviewers using it dailySeveral reviewers found the hold too light to keep style or curls in place, saying it did little compared with a firmer spray.
reviewers wanting more than a light holdThe fragrance is a big draw for many reviewers, though a few found it unbearable, unpleasant, or absent altogether.

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.
- 2 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 1 editorial), last checked 2026-10-17.
- Ingredient references are linked for 6 of 13 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 2026-10-17.
