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 Little

Nothing here is built to reduce combing force.

Oils and butters Present, high in the list

Oils sit high in the list: a softening, coating formula.

Weight on the hair Rich

Heavy butters and waxes in the first eight ingredients.

Water-binding (humectants) None found

No humectants, so nothing here pulls water into the hair.

Protein None

No protein or amino acids in the list.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Hard-water defence None

No chelating agent in the list.

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.

IngredientWhat it doesWhy it mattersChip
Olea Europaea (Olive) Oil oil Coats and softens the strand Softens
Arctium Lappa Fruit ExtractArctium Lappa Fruit (Burdock) Extract botanical extract A plant extract, there as much for marketing as for function Neutral
Ricinus Communis (Castor) Seed Oil oil Coats and softens the strand Softens
Pimpinella Anisum OilPimpinella Anisum (Anise) Oil essential oil — Softens
Melaleuca Alternifolia (Tea Tree) Leaf Oil botanical extract A trace plant extract Fragrance
What the list leaves out, and what it carriesThe list carries no sulfates, silicones, or drying alcohols. No protein: a moisture formula, not a repair one. Heavier butters sit in the working part of the list. Vegan and cruelty-free.
Full ingredient list (5)

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 Olea Europaea (Olive) Oil
    General function

    The oil pressed from Olive (Olea Europaea). It is one of the heavier plant oils — rich on coarse or dry hair, and enough to flatten fine hair.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • oil
    • emollient
  • 2 Arctium Lappa Fruit Extract · Arctium Lappa Fruit (Burdock) Extract
    General function

    Burdock fruit extract, a traditional scalp botanical. It is included for that reputation rather than for a measured effect on hair.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • botanical extract
  • 3 Ricinus Communis (Castor) Seed Oil
    General function

    A thick, tacky oil used for sealing ends and for slick, held-down styles.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    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
  • 4 Pimpinella Anisum Oil · Pimpinella Anisum (Anise) Oil
    General function

    Anise essential oil, used for its liquorice-like scent. Like other essential oils it can irritate a reactive scalp.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    • essential oil
    • oil
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 5 Melaleuca Alternifolia (Tea Tree) Leaf Oil
    General function

    Tea tree essential oil, used in scalp products for its sharp scent and traditional clarifying reputation.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May not suitFragrance-sensitive routines

    Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.

    • botanical extract
    • essential oil
    • fragrance

What the whole list adds up to

  • 3 oils
  • 2 emollients
  • 2 botanical extracts
  • 2 essential oils

Where we’ve seen it4 listings · 4 stores

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. 1.69 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. Commonly seen is the middle half of current prices for the 1.69 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
  3. Good value under $5 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.07/oz; at 1.69 oz that is $5. Under that line you are paying less than most of them.
  4. About $12 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1.69 oz.

How the score is counted

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.

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 to read this

We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.

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.
  • 7 sources consulted for this product (3 manufacturer or regulatory, 2 retailer, 2 editorial), last checked 2026-09-05.
  • Ingredient references are linked for 0 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 2026-09-05.
