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.
Water-first and light: unlikely to flatten fine hair.
Conditioning agents sit high in the list, so this is a detangling formula.
No humectants, so nothing here pulls water into the hair.
No oils or butters in the list.
No protein or amino acids in the list.
Nothing here needs a detergent wash to remove.
No fragrance is listed.
Ingredients that matter
The ingredients that change a decision
The workhorse ingredients, plus anything lower down that changes a decision. The 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 |
|---|---|---|---|
| WaterWater / Eau | solvent | The base everything else is dissolved in | Neutral |
| Cetearyl Alcohol | fatty alcohol | Thickens and conditions (not a drying alcohol) | Softens |
| Behentrimonium Chloride | conditioning agent | Conditions and softens so hair combs through | Detangles |
| Benzyl Alcohol | preservative | Keeps the product from spoiling | Stabilizes |
Full ingredient list (4)
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.

Water
· Water / 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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent

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.

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.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
International Journal of Cosmetic ScienceMay suitDry, coarse, or high-porosity hairElectrokinetic 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 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.

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
- 5.07 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 is the price we have observed for the 5.07 oz. We need three stores before we call a price commonly seen.
- Good value under $11 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.22/oz; at 5.07 oz that is $11. Under that line you are paying less than most of them.
- About $14 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 5.07 oz.
Formula
The formula carries what a leave-in is built around, and 6 products we score as close matches cost at least a quarter less per ounce. The difference is the label, not the formula.
How the score is counted
- 6 products we score as doing the same job cost less per ounce
- Costs more per ounce than 89% of the 749 leave-ins we’ve priced
- Covers 5 of the 6 things a leave-in should do
- Salon tier, sold at Brand website
- 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
- Oils or butters in the working zoneSoftens the strand rather than just coating it.2 pts
- No detergent-dependent filmNothing that needs a clarifying wash to remove.1 pt
- 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.
Does the same job, for less
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

Final decision
Should you buy it?
Good for the right person, not the lowest costPeople sensitive to fragrance, for a formula with no added fragrance and a protein-free formula
Not ideal for soft, over-stretchy hair that needs protein, very dry hair that needs water-binding, or coarse, very dry hair that wants real richness

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 (1 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-10-08.
- Ingredient references are linked for 2 of 2 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.
