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 found — 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. These 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, marketed as much as functional 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)

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

  • 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 this point, order stops being meaningful — these are typically 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
  • 1 fragrance

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 — the cheapest quarter and the dearest quarter are left out, 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 $2.78/oz; at 1.69 oz that is $5. Under that line you are paying less than most of them.
  4. About $7 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1.69 oz.

The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.

Does the same job, for less

Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Final decision

Should you buy it?

Good for the right person, not the lowest cost
Best user

People sensitive to fragrance — for a formula with no added fragrance and a protein-free formula

Biggest tradeoff

Not ideal for anyone sensitive to fragrance, oily scalps and fine hair, or people shopping on a budget

Best alternative if not

Consider TGIN Jamaican Black Castor Oil Growth Serum, for similar results at a lower price

Claims check

What the brand says, against what the formula shows

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

How this page was made

  • Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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 conditional formulation guidance, not a conclusion about the finished product or about you.
  • We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
  • 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 v22. Record last updated 2026-09-05.
