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 Rich

Butters near the top: a heavy, softening formula.

Weight on the hair Rich

Heavy butters and waxes in the first eight ingredients.

Protein Minor

Protein appears, low enough to be a supporting ingredient.

Water-binding (humectants) High

Humectants near the top — water-binding is a headline mechanism here.

Slip and detangling Little

Nothing here is built to reduce combing force.

Time on the hair 15 min

Long enough that it is a planned step, not a shower add-on.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

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.

Full ingredient list (12)

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 Water
    General function

    The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

    Leading ingredient

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

    • solvent
  • 2 Cocos Nucifera (Coconut) Oil · 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.

    International Journal of Trichology
    • oil
    • emollient
  • 3 Butyrospermum Parkii (Shea) Butter · Shea Butter
    General function

    A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.

    Leading ingredient

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

    May suitDry, coarse, or high-porosity hair

    Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.

    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 suitVery dry or highly damaged hair

    A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

    • butter
    • emollient
    • sealant
  • 4 Glycerin
    General function

    A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.

    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

    High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.

    May suitVery dry or highly damaged hair

    Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.

    DependsClimate-sensitive or frizz-prone hair

    Water moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.

    Scientific Reports
    • humectant
  • 5 Ricinus Communis (Castor) Seed Oil · Castor Seed Oil
    General function

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

    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
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 6 Mentha Piperita (Peppermint) Oil · Peppermint Leaf Extract
    General function

    Peppermint essential oil, used for scent and the cooling feeling on the scalp.

    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
  • 7 Persea Gratissima (Avocado) Oil · Avocado Oil
    General function

    A rich oil used in masks and heavier creams for softness on coarse or dry hair.

    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 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.

    • oil
    • emollient
  • 8 Mangifera Indica (Mango) Seed Butter · Mango Seed Butter
    General function

    A plant butter that is slightly lighter than shea, used in curl creams.

    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 suitDry, coarse, or high-porosity hair

    Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.

    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 suitVery dry or highly damaged hair

    A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

    • butter
    • emollient
  • 9 Olea Europaea (Olive) Fruit Oil · Olive Fruit Oil
    General function

    A heavy, coating oil traditionally used for deep conditioning.

    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 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

    • oil
    • emollient
  • 10 Buriti Fruit Oil
    • oil
    • emollient
  • 11 Hydrolyzed Keratin
    General function

    Fragments of the same protein hair is made of. They fill gaps on damaged strands and make hair feel firmer for a few washes.

    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 suitFrizz-prone, damaged, or high-friction hair

    Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

    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.

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 1 listing we don’t count — grey-market or unverified sellers.

How we work this out
  1. 11.5 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 11.5 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 $14 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.26/oz; at 11.5 oz that is $14. Under that line you are paying less than most of them.
  4. About $28 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 11.5 oz.

Final decision

Should you buy it?

A solid pick for the hair it suits
Best user

People sensitive to fragrance who want a formula with no added fragrance and a product with no scent

Biggest tradeoff

Not ideal for oily scalps and fine hair, hair that tangles the moment it is wet, or very dry or very humid climates

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 (4 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 3 of 10 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 2026-08-25.
