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.

Oils and butters Present, high in the list

Oils sit high in the list — a softening, coating formula.

Weight on the hair Rich

Heavy butters and waxes in the first eight ingredients.

Protein None

No protein or amino acids in the list.

Water-binding (humectants) High

Humectants near the top — water-binding is a headline mechanism here.

Slip and detangling High

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

Time on the hair 3–5 min

A short wait — it fits inside an ordinary shower.

Needs detergent to remove Yes

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

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. These 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 (31)

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.

1 Water

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 Cetearyl Alcohol

General function
A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.

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

May suitDry, coarse, or high-porosity hair
The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.

May suitFrizz-prone, damaged, or high-friction hair
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

DependsFine or easily flattened hair
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.

PubChem
- fatty alcohol
- emollient
- thickener
3 Glycerin

General function
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.

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

May suitDry, coarse, or high-porosity hair
High-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 hair
Binds 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 hair
Water 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.

Scientific Reports
- humectant
4 Palm Oil

General function
A heavy, sealing plant fat used in rich creams and butters.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- oil
- emollient
- sealant
5 Behentrimonium Chloride

General function
A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.

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

May suitDry, coarse, or high-porosity hair
Electrokinetic measurement puts the C22 quat ahead of the C16 ones for deposition: the longer chain adds van der Waals stabilisation on top of the charge binding. That extra deposit is what coarse hair usually needs to comb through.

May suitFrizz-prone, damaged, or high-friction hair
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

DependsBuild-up-sensitive routines
Substantive by design. A routine with no detergent wash gives it nothing to leave with.

International Journal of Cosmetic Science
- conditioning agent
- cleanser
6 Distearyldimonium Chloride

General function
A rich conditioning agent used in heavier masks for detangling and a coated, smooth feel.

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

May suitFrizz-prone, damaged, or high-friction hair
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

May suitVery dry or highly damaged hair
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

DependsBuild-up-sensitive routines

7 Persea Gratissima (Avocado) Oil · Avocado Oil

General function
A rich oil used in masks and heavier creams for softness on coarse or dry hair.

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

May suitDry, coarse, or high-porosity hair
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

May suitFrizz-prone, damaged, or high-friction hair
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

May not suitFine or easily flattened hair
Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.
- oil
- emollient
8 Cocos Nucifera (Coconut) Oil · Coconut Oil

General function
One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.

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

May suitDry, coarse, or high-porosity hair
Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.

May suitFrizz-prone, damaged, or high-friction hair
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

May suitVery dry or highly damaged hair
The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.

International Journal of Trichology
- oil
- emollient
9 Simmondsia Chinensis (Jojoba) Seed Oil · Jojoba Seed Oil

General function
Not chemically an oil: about 97% of it is liquid wax esters, which is why it resists going rancid and sits close to the scalp's own sebum. It smooths without a heavy finish.

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

May suitDry, coarse, or high-porosity hair
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

May suitFrizz-prone, damaged, or high-friction hair
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

May suitMaximum-hold styling
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.

11 Butyrospermum Parkii (Shea) Butter · Shea Butter

General function
A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

May suitDry, coarse, or high-porosity hair
Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

May suitVery dry or highly damaged hair
A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.
- butter
- emollient
- sealant
12 Behenyl/Octyldodecyl Propanediol Citrate Crosspolymer

General function
A synthetic film-forming polymer. Polymers of this kind dry to a continuous film on the hair, which is how a styling product holds a shape.

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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.

14 Hydroxypropyltrimonium Hydrolyzed Corn Starch

General function
A corn starch given a positive charge so it deposits on hair for slip and light body.

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
Adds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.

May suitFrizz-prone, damaged, or high-friction hair
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

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

22 Polyquaternium-37

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

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
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.

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

6.7 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 $41.65 is the price we have observed for the 6.7 oz. We need three stores before we call a price commonly seen.
Good value under $5 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.82/oz; at 6.7 oz that is $5. 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 $7 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 6.7 oz.

Formula

Formula score

8 of 10

The formula carries what a treatment is built around, and 7 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.

How the score is counted

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.

Final decision

Should you buy it?

Good for the right person, not the lowest cost

Best user

Hair that stiffens on protein, looking for a protein-free formula and real detangling slip

Biggest tradeoff

Less suited to anyone sensitive to fragrance, oily scalps and fine hair, or anyone stretching time between washes

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 (3 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
Ingredient references are linked for 14 of 22 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.
