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.
Cleansing strength
None
No detergent. The conditioners do the cleaning.
Slip and detangling
High
Conditioning agents sit high in the list, so this is a detangling formula.
Oils and butters
Present, high in the list
Oils sit high in the list: a softening, coating formula.
Water-binding (humectants)
High
Humectants near the top: binding water is one of its main jobs.
Weight on the hair
Medium
Middle of the range: noticeable on fine hair, light on coarse hair.
Needs detergent to remove
No
Nothing here needs a detergent wash to remove.
Protein
None
No protein or amino acids in the list.
Fragrance

Fragrance is listed; it sits below the working ingredients.

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.

Full ingredient list (15)
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
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
Organic Aloe Leaf Juice
General function
The juice pressed from Organic Aloe's leaf. Used in place of some of the water in a formula, so it often sits high on the list.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- botanical extract
- humectant
-
3
Behentrimonium Chloride
General function
A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
International Journal of Cosmetic ScienceMay suitDry, coarse, or high-porosity hairElectrokinetic measurement puts the C22 quat ahead of the C16 ones for deposition: the longer chain adds van der Waals stabilisation on top of the charge binding. That extra deposit is what coarse hair usually needs to comb through.
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.
DependsBuild-up-sensitive routinesSubstantive by design. A routine with no detergent wash gives it nothing to leave with.
- conditioning agent
- cleanser
-
4
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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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

5
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

Rhassoul Clay
General function
A Moroccan mineral clay traditionally used to wash hair. It absorbs oil and lifts residue without detergent.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- clay
- absorbent
-
7
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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

Vitis Vinifera (Grape) Seed Oil
· Grapeseed Oil
General function
A light oil used where softness is wanted without weight.
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.

Persea Gratissima (Avocado) Oil
· Avocado Oil
General function
A rich oil used in masks and heavier creams for softness on coarse or dry hair.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

Guar Hydroxypropyltrimonium Chloride
General function
A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitCurls or waves needing flexible holdGums thicken and set soft, which gives definition that bends rather than a rigid cast.
May suitFrizz-prone, damaged, or high-friction hairCationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
May suitMaximum-hold stylingA styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.

Fragrance
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 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 not suitFragrance-sensitive routinesEssential 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.

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
- 8 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 $14.99 is the price we have observed for the 8 oz. We need three stores before we call a price commonly seen.
- Good value under $8 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $1.05/oz; at 8 oz that is $8. Under that line you are paying less than most of them.
- About $14 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8 oz.

Formula score

The formula carries the systems a co-wash is built around, and it sits in the middle of the range for co-washes per ounce.
How the score is counted
- 3 products we score as doing the same job cost less per ounce
- Costs more per ounce than 56% of the 98 co-washes we’ve priced

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.

What the brand says, and what the formula shows
Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

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.
- 4 sources consulted for this product (4 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-25.
- Ingredient references are linked for 4 of 9 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.
