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 Light esters

Light esters or a volatile carrier: shine with little residue.

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 Present

Fragrance is listed; it sits below the working ingredients.

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 (15)

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 Caprylic/Capric Triglyceride
    General function

    A light, refined coconut-derived oil that spreads easily and does not go rancid. It gives slip without a heavy feel.

    Leading ingredient

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

    May suitFine or easily flattened hair

    A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

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

    Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

    • light ester
    • emollient
  • 2 Capryloyl Glycerin/Sebacic Acid Copolymer
    General function

    A plant-derived polymer that forms a light film and helps hold a style without a stiff feel.

    Leading ingredient

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

    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 suitMaximum-hold styling

    Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

    DependsCurls or waves needing flexible hold

    How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.

    • film former
    • emollient
  • 3 Diheptyl Succinate
    General function

    A light plant-derived ester used as a silicone alternative for slip and a dry, smooth finish.

    Leading ingredient

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

    May suitFine or easily flattened hair

    A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

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

    Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

    • light ester
    • emollient
  • 4 Isononyl Isononanoate
    General function

    A very light, dry-feeling ester used where a silky finish without weight is wanted.

    Supporting ingredient

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

    May suitFine or easily flattened hair

    A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

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

    Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

    • light ester
    • emollient
  • 5 Sclerocarya Birrea (Marula) Seed Oil
    General function

    Marula oil - light, stable, used for shine and softness.

    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
  • 6 Propylene Glycol Dibenzoate
    General function

    A light ester used for shine and slip in finishing products.

    Supporting ingredient

  • 7 Linoleic Acid
    General function

    An essential fatty acid found in most plant oils, used for softness and to support the hair's surface lipids.

    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

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    • emollient
  • 8 Linolenic Acid
    General function

    An omega-3 fatty acid from plant oils, used for softness at low levels.

    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

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. 1.7 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 $39.95 is the price we have observed for the 1.7 oz. We need three stores before we call a price commonly seen.
  3. Good value under $16 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $9.33/oz; at 1.7 oz that is $16. Under that line you are paying less than most of them.
  4. About $19 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1.7 oz.

Formula

Formula score
8 of 10

The formula carries what a hair oil is built around, and 6 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.

How the score is counted
  • 6 products we score as doing the same job cost less per ounce
  • Costs more per ounce than 92% of the 169 hair oils we’ve priced
  • Covers 5 of the 6 things a hair oil should do
  • Reviewers mention 4 things they like about how it performs
  • A shine systemThe silicone, oil, or ester that produces gloss.3 pts
  • A weightless carrierDelivers the shine without leaving grease.2 pts
  • Oils or butters in the working zoneSoftens the strand rather than just coating it.2 pts
  • An antioxidantKeeps the oils in the bottle from going off.1 pt
  • No drying alcohol in the first threeFast drying without leading on alcohol.1 pt
  • Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt

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.

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.

Customers describe it as lightweight and hydrating with a pleasant fragrance, and say a little goes a long way, making it good value despite the price

aggregate of Ulta/Amazon customer reviews

A reviewer with fine, curly hair said the product is not heavy or greasy, while a different reviewer with very fine hair found it made hair incredibly greasy

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.
  • 4 sources consulted for this product (0 manufacturer or regulatory, 4 retailer, 0 editorial), last checked 2026-08-27.
  • Ingredient references are linked for 7 of 14 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.
