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 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.

Slip and detangling Little

Nothing here is built to reduce combing force.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Fragrance Prominent

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

Full ingredient list (20)

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 Cocos Nucifera (Coconut) Oil
    General function

    One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive 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

    Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.

    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 suitVery dry or highly damaged hair

    The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.

    • oil
    • emollient
  • 2 Sesamum Indicum (Sesame) Seed Oil · Sesamum Indicum Seed Oil
    General function

    A medium-weight oil used for conditioning and scalp application.

    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
  • 3 Simmondsia Chinensis (Jojoba) Oil
    General function

    The oil pressed from Jojoba (Simmondsia Chinensis). It is one of the lighter plant oils, absorbing faster and leaving less residue.

    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.

    • emollient
  • 4 Helianthus Annuus (Sunflower) Seed Oil
    General function

    A light, widely used oil that softens without much weight.

    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.

  • 6 Corylus Avellana (Hazelnut) Seed Oil
  • 7 Schinziophyton Rautanenii Kernel Oil
    General function

    The oil pressed from Schinziophyton Rautanenii. 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.

    Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

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

    The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.

    May suitGray, silver, or brass-prone hair

    Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

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. and 3 listings we don’t count — grey-market or unverified sellers.

How we work this out
  1. 3.2 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 3.2 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 7 products we score as doing the same job as this one. A quarter of them cost less than $1.69/oz; at 3.2 oz that is $5. Under that line you are paying less than most of them.
  4. About $8 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 3.2 oz.

Final decision

Should you buy it?

Hard to justify at this price
Best user

Coarse, dry, or high-porosity hair, looking for a formula with real substance and a formula brought to an acidic pH

Biggest tradeoff

Less suited to anyone sensitive to fragrance, oily scalps and fine hair, or hair that tangles the moment it is wet

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.

Reviewers

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.

Reviewers report noticeably softer hair and reduced frizz after using it as a regular pre-shampoo or overnight treatment.

the brand's own review corpus (212 reviews, near-uniformly 5-star) on the product page

Reviewers use it for more than one purpose beyond a pre-shampoo treatment, mentioning it as an overnight mask and a sun/pool protectant.

the brand's own review corpus on the product page

Reviewers describe the fragrance as pleasant and not overpowering, calling it luxurious.

the brand's own review corpus on the product page

Some reviewers note the oil solidifies in cooler weather and needs warming (e.g. in hot water) before it spreads easily.

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.
  • 3 sources consulted for this product (1 manufacturer or regulatory, 0 retailer, 2 editorial), last checked 2026-09-17.
  • Ingredient references are linked for 11 of 16 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 2026-09-17.
