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.
Middle of the range: noticeable on fine hair, light on coarse hair.
Conditioning agents sit high in the list, so this is a detangling formula.
Humectants near the top: binding water is one of its main jobs.
Butters near the top: a heavy, softening formula.
Protein appears, low enough to be a supporting ingredient.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No fragrance is listed.

Full ingredient list (32)
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
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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent
-
2
Aloe Barbadensis Leaf Juice
General function
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitCurls or waves needing flexible holdGums thicken and set soft, which gives definition that bends rather than a rigid cast.
May suitFine or easily flattened hairHydration with no oil attached, so it adds very little weight even high on a list.
May suitVery dry or highly damaged hairAloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.
- humectant
- botanical extract

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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitDry, coarse, or high-porosity hairThe 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 hairDeposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
DependsFine or easily flattened hairNear the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.

C13-15 Alkane
General function
A plant-derived light alkane used as a clean-feeling replacement for silicone or mineral oil.
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.
- emollient
- solvent

Behentrimonium Methosulfate
· Behentrimonium Methosulphate
General function
A mild cationic conditioner known for heavy detangling with a light rinse-out feel. Common in curly-hair conditioners.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
International Journal of Cosmetic ScienceMay suitDry, coarse, or high-porosity hairA C22 conditioning quat, the chain length that deposits most heavily in electrokinetic testing. It is the slip coarse or porous hair usually needs, delivered by chain length rather than by charge alone.
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.
May suitVery dry or highly damaged hairThe class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

Butyrospermum Parkii (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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitDry, coarse, or high-porosity hairCoarse, 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 hairEmollients 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 hairA solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

Isopentyldiol
· Isopentydiol
General function
A light solvent and humectant used to dissolve extracts and improve feel.
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.
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.

Polyquaternium-10
· Polyquaternium 10
General function
A cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitCurls or waves needing flexible holdCationic 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 hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Simmondsia Chinensis (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 ingredientLower 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 hairCoats 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 hairA thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
May suitMaximum-hold stylingA wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.

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
- 12 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 12 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 $14 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $1.13/oz; at 12 oz that is $14. 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 $18 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 12 oz.
Formula
A complete formula at an ordinary price: mid-range per ounce among leave-ins, with the working systems in place.
How the score is counted
- 2 products that do the same job cost less per ounce
- Costs less per ounce than 71% of the 749 leave-ins we’ve priced
- Covers 5 of the 6 things a leave-in should do
- Reviewers mention 3 things they like about how it performs
- Conditioning agents up frontWhat makes wet hair comb through.2 pts
- A humectantBinds water into the hair.2 pts
- A light baseWater or a volatile carrier first, so it does not weigh hair down.2 pts

- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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.
- 3 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-31.
- Ingredient references are linked for 11 of 22 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 2026-10-07.
