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 Rich

Butters near the top: a heavy, softening formula.

Weight on the hair Medium

Middle of the range: noticeable on fine hair, light on coarse hair.

Protein None

No protein or amino acids in the list.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Slip and detangling High

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

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Fragrance None listed

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.

Full ingredient list (18)

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 · Deionized 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 Kaolin Clay
    • mineral
    • powder
  • 3 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
  • 4 Cetyl Alcohol
    General function

    A fatty alcohol used to thicken creams and add slip. It softens rather than dries.

    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

    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

    PubChem
    • fatty alcohol
    • emollient
    • thickener
  • 5 Dicetyldimonium Chloride
    General function

    A conditioning agent used for slip in thick creams and masks.

    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

    Substantive by design. A routine with no detergent wash gives it nothing to leave with.

    PubChem
    • conditioning agent
  • 6 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.

    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

    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
  • 7 Stearamidopropyl Dimethylamine
    General function

    A gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much build-up.

    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

    Substantive by design. A routine with no detergent wash gives it nothing to leave with.

    PubChem
    • conditioning agent
  • 8 Olea Europaea (Olive) Fruit Oil · Olive Oil
    General function

    A heavy, coating oil traditionally used for deep conditioning.

    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
  • 9 Avocado Butter
    • butter
    • emollient
  • 10 Guar Gum
    General function

    A bean gum that thickens and gives a slippery feel.

    Secondary ingredient

    Lower 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 hold

    Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

    • gum
    • thickener
  • 11 Polysorbate 60
    • emulsifier
    • solubilizer
  • 12 Panthenol · Panthenol (Pro-Vitamin B5)
    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 ingredient

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

    May suitFine or easily flattened hair

    It hydrates without adding oil or a film, which is the combination fine hair usually needs.

    May suitFrizz-prone, damaged, or high-friction hair

    Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

    May suitVery dry or highly damaged hair

    A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

Where we’ve seen it1 listing · 1 store

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
  1. 8 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.
  2. Seen at $30 is the price we have observed for the 8 oz. We need three stores before we call a price commonly seen.
  3. Good value under $18 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.25/oz; at 8 oz that is $18. Under that line you are paying less than most of them.
  4. About $30 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8 oz.

Both the formula and the price land mid-range: it covers the core of what a treatment does and costs about what masks and treatments cost per ounce.

How the score is counted
  • 3 products we score as doing the same job cost less per ounce
  • Costs more per ounce than 50% of the 576 masks and treatments we’ve priced

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.

We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.

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.

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 (2 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-10-04.
  • Ingredient references are linked for 5 of 8 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 2026-09-08.
