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.
Heavy butters and waxes in the first eight ingredients.
Some slip, mostly from esters or silicones rather than conditioners.
Humectants near the top: binding water is one of its main jobs.
Oils sit high in the list: a softening, coating formula.
No protein or amino acids in the list.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Fragrance is listed; it sits below the working ingredients.
Ingredients that matter
The ingredients that change a decision

Full ingredient list (21)
In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.
-
1
Water
· Deionized Water (Aqua)
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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent
-
2
Helianthus Annuus (Sunflower) Seed Oil
· Sunflower Seed Oil (Helianthus Annuus)
General function
A light, widely used oil that softens without much weight.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
International Journal of TrichologyMay suitDry, coarse, or high-porosity hairCoats 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 hairA 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 hairNear 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

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-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 hairBinds 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 hairWater 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.
- humectant

4
Steareth-2
General function
A fatty alcohol with ethylene oxide added. The number is how many units: low numbers sit on the oil side of an emulsion, high numbers dissolve in water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- emulsifier
-
5
Beeswax
· Beeswax (Cera Alba)
General function
A firm natural wax that grips and holds hair in place. It resists water and can take repeated washing to remove.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitMaximum-hold stylingA wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
May suitVery dry or highly damaged hairForms a physical barrier on the strand that slows water leaving it. Nothing else in a formula holds moisture in as bluntly.
May not suitBuild-up-sensitive routinesIt does not disperse in water at all: removing it means a detergent wash, and until then it stays exactly where it landed.

Isododecane
General function
A fast-evaporating carrier that lets oils and polymers spread thinly, then leaves nothing behind.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Steareth-20
General function
An emulsifier that keeps oils and water blended in a cream.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- emulsifier
-
8
Ethylhexyl Hydroxystearate
General function
A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- light ester

Olea Europaea (Olive) Fruit Oil
· Olive Oil (Olea Europaea Fruit Oil)

Cocos Nucifera (Coconut) Oil
· Coconut Oil (Cocos Nucifera)
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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
International Journal of TrichologyMay suitDry, coarse, or high-porosity hairBecause 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 hairA 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 hairThe 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.

13
Butyrospermum Parkii (Shea) Butter
· Shea Butter (Butyrospermum Parkii)
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.
Secondary ingredientLower 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 hairCoarse, 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 hairEmollients 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 hairA 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

14
Panthenol
· Panthenol (Provitamin B5)
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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.
May suitFrizz-prone, damaged, or high-friction hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
May suitVery dry or highly damaged hairA humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

Caprylhydroxamic Acid
General function
A coconut-derived preservative booster that also binds trace metals.

PubChemMay suitBuild-up-sensitive routinesBinds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
May suitGray, silver, or brass-prone hairCopper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.

Carbomer
General function
A thickener that turns a liquid into a clear gel. It also contributes a light hold.
Estimated lower-concentration zoneIt 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 hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
May suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

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.

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
- 12 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 12 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $19 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.55/oz; at 12 oz that is $19. Under that line you are paying less than most of them.
- About $38 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 12 oz.
Formula

How this page was made
- Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one 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.
- 1 source consulted for this product (0 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-10-07.
- Ingredient references are linked for 7 of 14 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- 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 v23. Record last updated 2026-10-07.
