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 Light

Water-first and light: unlikely to flatten fine hair.

Oils and butters Present, lower down

Oils are present, but low enough to be a finishing touch.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Full ingredient list (40)

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 Polysorbate 20

General function
Keeps fragrance and oils dissolved in a watery formula so it stays clear.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
- solubilizer
- emulsifier
3 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.

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

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
4 PEG-40 Hydrogenated Castor Oil

General function
A castor-oil derivative that dissolves fragrance and oils into water so the product stays clear and does not separate.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- solubilizer
- emulsifier
5 Propanediol

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

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
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
6 Octyldodecyl Citrate Crosspolymer

General function
A polymer ester that thickens oils into a gel and leaves a cushioned, glossy film.

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.

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.
- light ester
- film former
- thickener
7 Honey · Honey\Mel\Miel

General function
A natural sugar-based humectant that holds water against the strand.

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
Hydration with no oil attached, so it adds very little weight even high on a list.

May suitVery dry or highly damaged hair
Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.

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.

11 Aleurites Moluccanus (Kukui) Seed Oil · Aleurites Moluccanus Seed Oil

General function
Kukui nut oil - a light oil used for softness on fine textured hair.

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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.
- oil
- emollient
12 Helianthus Annuus (Sunflower) Seed Oil

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

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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.

DependsVery dry or highly damaged hair
It works on the surface. In the comparison that established coconut oil's penetration, sunflower oil did not reduce protein loss from washing — its fatty acids are bulkier and less linear. It softens and smooths; it does not reinforce the fibre.

14 Hydrogenated Castor Oil/Sebacic Acid Copolymer

General function
A castor-derived wax polymer that thickens balms and helps a style hold.

Secondary ingredient
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.

May not suitBuild-up-sensitive routines
Waxes do not dissolve in water. They need a detergent wash to come off, and they are the classic cause of a coated feel.

A sugar-derived conditioning agent used in bond-repair positioned formulas for moisture 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 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.

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.

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.

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 suitClimate-sensitive or frizz-prone hair

It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

DependsFrizz-prone, damaged, or high-friction hair
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not 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

1.62 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.
Commonly seen is the middle half of current prices for the 1.62 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.
Good value under $14 comes from the 6 products we score as doing the same job as this one. A quarter of them cost less than $8.79/oz; at 1.62 oz that is $14. Under that line you are paying less than most of them.
Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
About $32 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1.62 oz.

Final decision

Should you buy it?

An above-range pick for the hair it suits

Best user

Hair that stiffens on protein — for a protein-free formula and something that will not weigh hair down

Biggest tradeoff

Less suited to anyone sensitive to fragrance, anyone stretching time between washes, or very dry or very humid climates

Best alternative if not

Nothing in our library matches it closely at a lower price.

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 to read this

We look at the first 10–15 ingredients and what they do in a formula — not marketing. If the list doesn't speak to a claim, we don't assume.

Reviewers

What people report

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

Several reviewers describe the product leaving a sticky, heavy residue that feels like the previous product was never fully rinsed out.

Multiple reviewers say it noticeably reduces frizz and adds shine without weighing their hair down.

Several reviewers with dry or damaged hair say the oil made their hair feel noticeably healthier and more manageable over repeated use.

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.

Ingredient references are linked for 16 of 24 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.

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.
