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.
Softening ingredients sit alongside the film formers, so a hard shell is unlikely.
Water-first and light: unlikely to flatten fine hair.
No absorbent powders or starches.
Oils are present, but low enough to be a finishing touch.
No fast-drying alcohol in the list.
The silicones here are the water-soluble kind.
Fragrance is listed; it sits below the working ingredients.

Full ingredient list (45)
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.

VP/VA Copolymer
General function
A hold polymer that dries to a clear film. It sets the style and washes out with water.
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.

Ceteareth-20
General function
An emulsifier that holds oil and water together in a conditioner or cream.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- emulsifier
-
5
Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Role in this product typeIn styling gel, glycerin helps retain moisture as the product dries, supporting a softer, more flexible finish. The hold itself comes from the formula's film-forming polymers.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Cosmetic Ingredient ReviewMay suitDry, coarse, or high-porosity hairMay suit hair that benefits from added water retention and a softer, more flexible gel finish.
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 hairConsider the climate and the complete formula: prominent humectants can behave differently in very dry air and on frizz-prone hair in high humidity.

Propylene Glycol
General function
A small humectant and solvent that keeps formulas stable and helps active ingredients spread.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it adds less weight than oils or butters do.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

PEG-7 Glyceryl Cocoate
General function
A coconut-derived emulsifier that softens a cleanser and reduces the stripped feeling.
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 hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Peg-7 Hydrogenated Castor Oil
General function

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
- 8 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 $6.37 is the price we have observed for the 8 oz. We need three stores before we call a price commonly seen.
- Good value under $26 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.29/oz; at 8 oz that is $26. Under that line you are paying less than most of them.
- Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
- About $27 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8 oz.
Formula
This formula covers the systems a gel is built around, and it costs less per ounce than most of the gels we have researched.

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.

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, 0 retailer, 2 editorial), last checked 2026-10-08.
- Ingredient references are linked for 11 of 25 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.
