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.
Oils are present, but low enough to be a finishing touch.
Protein appears, low enough to be a supporting ingredient.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Fragrance is listed; it sits below the working ingredients.

VP/Dmapa Acrylates Copolymer
General function
A hold polymer that sets with some flexibility and washes out with water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitClimate-sensitive or frizz-prone hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
May 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.

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.

General function
A thickening polymer that gives creams and curl products their bounce and helps them cling to the strand.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

Benzalkonium Chloride
General function
A positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.

$43.006.76 oz · $6.36/ozOct 8
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
- 6.76 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 $43 is the price we have observed for the 6.76 oz. We need three stores before we call a price commonly seen.
- Good value under $10 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $1.46/oz; at 6.76 oz that is $10. Under that line you are paying less than most of them.
- About $13 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 6.76 oz.
Formula
This is a complete leave-in formula. It is also above the range for leave-ins per ounce, with 5 close matches selling for meaningfully less.
How the score is counted
- 5 products that do the same job cost less per ounce
- Costs more per ounce than 80% of the 749 leave-ins we’ve priced
- Covers 5 of the 6 things a leave-in should do
- Reviewers mention 2 recurring complaints
- 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.

What people report
Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.
Many reviewers say it smooths hair and tames frizz, especially for those who battle frizz regularly.
Reviewers with frizzy or frizz-prone hairSeveral reviewers say it feels heavy, waxy or greasy, especially on fine hair or when air dried.
Reviewers with fine hair or who air drySome reviewers say it did little for frizz or looked no different from other products they tried.
Reviewers across hair typesSeveral reviewers praise the smell, though the jasmine note is not to everyone's taste.

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 26 of 53 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 2026-10-08.
