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.

Heat protection Claimed, no temperature given

Sold as a heat protectant; no temperature is stated.

Full ingredient list (19)

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 · Water/Aqua/Eau

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 Coco-Glucoside

General function
A sugar-derived, low-foaming cleanser used in gentle and curly-method shampoos.

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

May suitDry, coarse, or high-porosity hair
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

May suitVery dry or highly damaged hair
A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.

May not suitBuild-up-sensitive routines
Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.

PubChem
- nonionic cleanser
- cleanser
3 Cetyl Alcohol

General function
A fatty alcohol used to thicken creams and add slip. It softens rather than dries.

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

May suitDry, coarse, or high-porosity hair
The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.

May suitFrizz-prone, damaged, or high-friction hair
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

DependsFine or easily flattened hair
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.

PubChem
- fatty alcohol
- emollient
- thickener
4 Oenocarpus Bataua (Ungurahua) Fruit Oil

General function
A light Amazonian fruit oil 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
▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
5 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.

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.

6 Plukenetia Volubilis (Sacha Inchi) Seed Oil

General function
A light seed oil rich in fatty acids, used for softness without much weight.

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

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.

8 Persea Gratissima (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.

9 Prunus Amygdalus Dulcis (Sweet Almond) Oil

General function
A medium-weight oil used for softness and slip.

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.

10 Hibiscus Sabdariffa Flower Extract
- botanical extract
11 Butyrospermum Parkii (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.

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
- sealant
12 Hydrolyzed Quinoa

General function
A quinoa-derived protein used for light strengthening and colour retention claims.

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.

May suitVery dry or highly damaged hair
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
- film former
- protein
- hydrolysed protein
13 Propanediol

General function
A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.

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 suitFine or easily flattened hair
Light and water-binding rather than oily, so it hydrates without contributing weight.

May suitVery dry or highly damaged hair
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

DependsClimate-sensitive or frizz-prone hair
A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

PubChem
- humectant
- solvent
14 Isopropyl Myristate

General function
A very light ester that makes products glide and disappear quickly on the 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 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.

PubChem
- light ester
- emollient
15 Fragrance · Fragrance/Parfum

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.
- fragrance
- declared fragrance
16 Stearalkonium Chloride

General function
A long-standing conditioning agent that flattens the cuticle and cuts static. It rinses less completely than newer alternatives.

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
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

May suitVery dry or highly damaged hair
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

DependsBuild-up-sensitive routines
Substantive by design. A routine with no detergent wash gives it nothing to leave with.

PubChem
- conditioning agent
17 Panthenol

General function
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

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 suitFine or easily flattened hair
It hydrates without adding oil or a film, which is the combination fine hair usually needs.

May suitFrizz-prone, damaged, or high-friction hair
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

May suitVery dry or highly damaged hair
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

PubChem
- humectant
- conditioning agent
- vitamin
18 Citric Acid

General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

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 suitBuild-up-sensitive routines
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.

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

6.5 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.
Seen at $40 is the price we have observed for the 6.5 oz. We need three stores before we call a price commonly seen.
Good value under $21 comes from the 6 products we score as doing the same job as this one. A quarter of them cost less than $3.18/oz; at 6.5 oz that is $21. Under that line you are paying less than most of them.
About $30 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 6.5 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.

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.
3 sources consulted for this product (3 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-25.
Ingredient references are linked for 7 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.
