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

Conditioning agents sit high in the list, so this is a detangling formula.
Oils and butters
None
No oils or butters in the list.

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 (Aqua) | 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 |
| Glycerin | humectant | Pulls water into the hair | Moisturizes |
| Pisum Sativum (Pea) Peptide | protein | Firms up soft, over-stretchy hair | Protein |
| Hydrolyzed Rice Protein | film former | Lays down the film that holds a shape | Protein |
| Niacinamide | vitamin | A marketed vitamin addition | Detangles |
| Dimethicone | silicone | Smooths the cuticle and adds shine | Buildup |
| Fragrance | fragrance | The scent | Fragrance |
What the list leaves out, and what it carriesNo sulfates or drying alcohols. Protein-forward: a strengthening formula, not a moisture one. Contains fragrance. The silicones here need a detergent wash to come off.
Full ingredient list (17)
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)
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
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.
Role in this product typeIn conditioner, cetearyl alcohol gives the emulsion its creamy structure and helps it spread evenly through the hair. Its emollient layer adds slip and a smoother feel.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
BASFMay suitDry, coarse, or high-porosity hairMay suit dry, coarse, or high-porosity hair that benefits from added slip and a more substantial conditioning film.
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 hairConsider if hair is fine or easily flattened: a formula built heavily around fatty alcohols can feel richer than a lightweight conditioner.

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.

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.

Pisum Sativum (Pea) Peptide
General function
A short-chain pea protein used for strength and body claims in vegan formulas.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May not suitProtein-sensitive hairA large surface-depositing protein. If protein reliably makes your hair feel rigid, this is the form most likely to do it.
DependsVery dry or highly damaged hairUnhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.
- protein

Hydrolyzed Rice Protein
General function
A light plant protein that adds body and shine, popular in volume products.
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 hairFilling 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 stylingFilm 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 hairHydrolysed 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.

Niacinamide
General function
Vitamin B3, used in scalp products for conditioning claims.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFrizz-prone, damaged, or high-friction hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

Dimethicone
General function
The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitClimate-sensitive or frizz-prone hairA 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 hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
May not suitBuild-up-sensitive routinesDimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.

Stearamidopropyl Dimethylamine
General function
A gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much build-up.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
PubChemMay 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.

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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.

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.

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
- 13 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 13 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 $10 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.77/oz; at 13 oz that is $10. Under that line you are paying less than most of them.
- About $12 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 13 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.

Reviewers
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 the conditioner leaves hair silky, soft and shiny, with an easy rinse.
Reviewers across hair typesSome reviewers say it weighed hair down, left residue or buildup, and made styling flat.
Reviewers across hair typesSome reviewers say it felt drying, leaving hair rough, dull or straw-like rather than conditioned.
Reviewers across hair typesReviewers are split on detangling: some say tangles stayed stuck, while others found it easy to comb through.
Reviewers across hair typesScent draws mixed reactions: several reviewers like the fresh, pleasant smell, while some find it too strong or medicinal.

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 (0 manufacturer or regulatory, 4 retailer, 0 editorial), last checked 2026-10-31.
- Ingredient references are linked for 9 of 14 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 2026-08-25.
