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.

Slip and detangling High

Conditioning agents sit high in the list, so this is a detangling formula.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Fast-drying alcohol Present

Contains fast-drying alcohol, which speeds drying but can leave hair feeling dry.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Full ingredient list (34)

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 Water · Water (Aqua, 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
2 VP/VA Copolymer

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

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

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
3 Polyquaternium-37

General function
A thickening polymer that gives creams and curl products their bounce and helps them cling to the strand.

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

May suitCurls or waves needing flexible hold
Cationic 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 hair
A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
- conditioning agent
- film former
- polymer
- thickener
4 PEG-60 Hydrogenated Castor Oil

General function
A castor-derived solubiliser that keeps fragrance and oils dissolved in clear liquids.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- solubilizer
- emulsifier
5 Bis-PEG/PPG-20/20 Dimethicone
6 Phenyl Trimethicone

General function
A high-refractive silicone used specifically for visible shine in serums and finishing oils.

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 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
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

May not suitBuild-up-sensitive routines
Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
- silicone
- emollient
7 Dimethicone PEG-8 Meadowfoamate

General function
A silicone modified with meadowfoam oil, used for shine with a lighter feel.

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 surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

8 Propylene Glycol Dicaprylate/Dicaprate

General function
A light, dry-feeling ester that spreads other ingredients and softens without a greasy finish.

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

May suitFine or easily flattened hair
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

May suitFrizz-prone, damaged, or high-friction hair
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

10 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.

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.

11 Caprylyl Glycol

General function
A gentle preservative helper that also holds a little moisture.

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 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

12 Guar Hydroxypropyltrimonium Chloride

General function
A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.

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 suitCurls or waves needing flexible hold
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

May suitFrizz-prone, damaged, or high-friction hair
Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.

May suitMaximum-hold styling
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.

14 Hydroxyethylcellulose

General function
A cellulose thickener that gives gels and conditioners their body and adds a soft, flexible film.

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 suitCurls or waves needing flexible hold
A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.

May suitFrizz-prone, damaged, or high-friction hair
A soft film binds neighbouring strands together, which is most of what helps flyaways lie down.

May not suitMaximum-hold styling
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.

16 Disodium EDTA

General function
Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.

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
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.

May suitGray, silver, or brass-prone hair
Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.

PubChem
- hard-water chelator
17 Tetramethyl Acetyloctahydronaphthalenes

General function
A synthetic musk or woody-amber note used as a fragrance base.

20 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.

22 Sodium Acetate

General function
A buffering salt used to hold the formula at a steady pH.

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.

23 Citrus Limon (Lemon) Peel Oil

General function
A cold-pressed citrus oil used for a fresh scent; naturally high in limonene.

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

32 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

33 Hydrolyzed Lupine Protein

General function
A protein broken into fragments small enough to cling to the hair. It fills gaps on damaged strands and firms the feel for a few washes; too much reads as stiff.

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
Filling 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 styling
Film 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 hair
Hydrolysed 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.

34 1,2-Hexanediol

General function
A preservative booster that also holds a little moisture and helps other ingredients dissolve.

Estimated lower-concentration zone

May suitFine or easily flattened hair
Light and water-binding rather than oily, so it adds less weight than oils or butters do.

May suitVery dry or highly damaged hair
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

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

6 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 6 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 $51 comes from the 4 products we score as doing the same job as this one. A quarter of them cost less than $8.54/oz; at 6 oz that is $51. Under that line you are paying less than most of them.
About $59 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 6 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 to read this

We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.

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 (2 manufacturer or regulatory, 1 retailer, 1 editorial), last checked 2026-10-22.
Ingredient references are linked for 9 of 26 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.
