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.

Shine system Oil blend

A silicone or oil blend does the shine work here.

Weight on the hair Rich

Heavy butters and waxes in the first eight ingredients.

Oils and butters Present, high in the list

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

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Fragrance Prominent

Fragrance sits in the first eight ingredients — a larger share of the formula.

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.

Full ingredient list (9)

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 Organic Calendula Officinalis Flower Oil
    General function

    The essential oil of Organic Calendula. Essential oils are aromatic — they are in the formula for scent, and they are a common source of declared fragrance allergens.

    Leading ingredient

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

    • fragrance
    • botanical extract
  • 2 Organic Decolorized Aloe Barbadensis Leaf Oil
    General function

    The essential oil of Organic Decolorized. Essential oils are aromatic — they are in the formula for scent, and they are a common source of declared fragrance allergens.

    Leading ingredient

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

    • fragrance
    • botanical extract
  • 3 Organic Cocos Nucifera (Coconut) Fruit Oil
    General function

    The oil pressed from Organic Cocos. 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
  • 4 Organic Rosmarinus Officinalis (Rosemary) Leaf Extract
    General function

    An extract from the leaf of Organic Rosmarinus. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Supporting ingredient

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

    • botanical extract
  • 5 Oenocarpus Bataua (Rahua Ungurahua) Oil
    General function

    The oil pressed from Rahua Ungurahua (Oenocarpus Bataua). How much weight a plant oil leaves depends on the hair it lands on; coarse hair tends to take more of it than fine hair.

    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.

    • emollient
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 6 Mauritia Flexuosa (Buriti) Fruit Oil · Mauritia Flexuosa (Morete) Fruit Oil
    General function

    A rich orange fruit oil used in small amounts in curl and colour-care products.

    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.

    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.

    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

    Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

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. 1.6 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 1.6 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 $2.91/oz; at 1.6 oz that is $5. Under that line you are paying less than most of them.
  4. About $11 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1.6 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

Hair that stiffens on protein who want a protein-free formula and a formula with real substance

Biggest tradeoff

Not ideal for anyone sensitive to fragrance, oily scalps and fine hair, or frizz on humid days

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, 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.
  • 2 sources consulted for this product (1 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-27.
  • Ingredient references are linked for 0 of 4 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 2026-08-27.
