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.

Ingredients that matter
The ingredients that change a decision
The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| WaterAqua (Water) | solvent | The base everything else is dissolved in | Neutral |
| Isopentyldiol | solvent | The base everything else is dissolved in | Moisturizes |
| Oleth-10 | emulsifier | Keeps oil and water mixed | Stabilizes |
| Ethylhexylglycerin | preservative | Keeps the product from spoiling | Shine |
| Fragrance | fragrance | The scent | Fragrance |

What the list leaves out, and what it carriesThe list carries no sulfates or drying alcohols. Protein sits high: this is a strengthening step rather than a moisture one. Fragrance is on the label. Water-insoluble silicones — needs a detergent wash to remove.
Full ingredient list (15)
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

Isopentyldiol
General function
A light solvent and humectant used to dissolve extracts and improve feel.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it hydrates without contributing weight.
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.
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.

Oleth-10
General function
An emulsifier used to disperse oils and fragrance.

Ethylhexylglycerin
General function
A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.
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 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.

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.

Pisum Sativum (Pea) Peptide
General function
A short-chain pea protein used for strength and body claims in vegan formulas.
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.
DependsVery dry or highly damaged hairUnhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.

Hydrolyzed Rice Protein
General function
A light plant protein that adds body and shine, popular in volume products.
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 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.
May suitVery dry or highly damaged hairHydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.

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

Propoxytetramethyl Piperidinyl Dimethicone
General function
A silicone. Silicones coat the strand for slip, shine and frizz control; unless the name carries PEG or PPG, removing one takes a detergent rather than 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.
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.

Cetrimonium Chloride
General function
A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.
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 suitFine or easily flattened hairThe C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.
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.
DependsBuild-up-sensitive routinesSubstantive by design. A routine with no detergent wash gives it nothing to leave with.
- conditioning agent
- cleanser

PVP
General function
A classic hairspray polymer. It gives firm hold but attracts moisture, so humidity can soften the set.
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 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.
DependsCurls or waves needing flexible holdIt sets firm on its own. Whether the curl stays flexible depends on the plasticisers and oils the rest of the formula carries.

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.

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
- 0.33 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 0.33 oz at recognised stores — the cheapest quarter and the dearest quarter are left out, so one sale or one overpriced listing can’t move it.
- Good value under $2 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $5.34/oz; at 0.33 oz that is $2. 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 $4 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 0.33 oz.

The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

How this page was made
- Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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 (0 manufacturer or regulatory, 4 retailer, 0 editorial), last checked 2026-09-05.
- Ingredient references are linked for 7 of 11 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
- We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
- 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 v22. Record last updated 2026-09-06.
