Wash day
How it fits into wash day
Read from the product’s own directions on the date shown. A step the label leaves out is shown as not stated, never filled in.
- When
- Before shampoo: Conditioning the lengths
- Start on
- damp hair
- Where
- lengths
- Label wait
- at least 20 minutes (longer allowed)
- Then
- shampoo it out
- Needs
- a shampoo and a conditioner
- Conditioner after
- yes, the label says to condition after shampooing it out
- How often
- not stated on the label
- Worth knowing
- Overnight use is allowed by the label. Designed to be shampooed away; the brand says it is too heavy for most hair types to rinse off without shampoo.
- Apply to damp hair.
- Leave for at least 20 minutes; longer is fine, including overnight under a wrap.
- Wash out with a shampoo (fine hair: shampoo twice).
- Condition and style as normal.

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
Present, high in the list
Oils sit high in the list: a softening, coating 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: binding water is one of its main jobs.
Slip and detangling
Moderate
Conditioning agents are present, lower in the list.
Needs detergent to remove
Yes
Water-insoluble silicones or waxes: a detergent wash is what removes them.
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. The chips name what an ingredient does. They are not safety scores, and no ingredient here is rated good or bad on its own.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| WaterAqua/Water/Eau | solvent | The base everything else is dissolved in | Neutral |
| Ricinus Communis (Castor) Seed Oil | oil | Coats and softens the strand | Softens |
| Cetearyl Alcohol | fatty alcohol | Thickens and conditions (not a drying alcohol) | Softens |
| Glycerin | humectant | Pulls water into the hair | Moisturizes |
| Propylene Glycol | humectant | Pulls water into the hair | Moisturizes |

What the list leaves out, and what it carriesNo sulfates, drying alcohols, or fragrance. Contains heavier butters. The silicones here need a detergent wash to come off.
Full ingredient list (18)
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
· Aqua/Water/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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent

2
Ricinus Communis (Castor) Seed Oil
General function
A thick, tacky oil used for sealing ends and for slick, held-down styles.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May 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.

Cetearyl Alcohol
General function
A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitDry, coarse, or high-porosity hairThe 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 hairDeposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
DependsFine or easily flattened hairNear the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.
- fatty alcohol
- emollient
- thickener

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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

Propylene Glycol
General function
A small humectant and solvent that keeps formulas stable and helps active ingredients spread.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it adds less weight than oils or butters do.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
DependsClimate-sensitive or frizz-prone hairA 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.

Olea Europaea (Olive) Fruit Oil
· Olea (Olive) Europaea Fruit Oil
General function
A heavy, coating oil traditionally used for deep conditioning.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May 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.

Ethylhexyl Dimethyl PABA
General function
A UV filter used in leave-on hair products to slow colour fade.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitGray, silver, or brass-prone hairSunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.
- UV filter

Amodimethicone
General function
A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

Polyquaternium-37
General function
A thickening polymer that gives creams and curl products their bounce and helps them cling to the strand.
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 suitCurls or waves needing flexible holdCationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
May suitFrizz-prone, damaged, or high-friction hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

Cetrimonium Chloride
General function
A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.
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.
International Journal of Cosmetic ScienceMay suitFine or easily flattened hairThe C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.
May suitFrizz-prone, damaged, or high-friction hairA cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

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 suitFrizz-prone, damaged, or high-friction hairFilling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
May suitVery dry or highly damaged hairHydrolysed 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.

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
- 5.07 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 $58 is the price we have observed for the 5.07 oz. We need three stores before we call a price commonly seen.
- Good value under $4 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.73/oz; at 5.07 oz that is $4. 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 $7 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 5.07 oz.

The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.
Does the same job, for less
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

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.
- 5 sources consulted for this product (4 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
- Ingredient references are linked for 6 of 13 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 2026-08-25.
