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
Medium
Middle of the range: noticeable on fine hair, light on coarse hair.
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
High
Conditioning agents sit high in the list, so this is a detangling formula.
Time on the hair
3–5 min
A short wait that fits inside an ordinary shower.
Needs detergent to remove
Yes
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Fragrance

What the list leaves out, and what it carriesNo sulfates. Contains fragrance. The silicones here need a detergent wash to come off. Chelators for hard water.
Full ingredient list (56)
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
Outer Tube: Aqua/Water
General function
Water distilled with Outer Tube, standing in for some of the plain water in the formula. It carries scent and marketing more than measurable effect.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- botanical extract
-
2
Cetearyl Alcohol
· OUTER TUBE: 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
-
3
Aminopropyl Triethoxysilane
· OUTER TUBE: Aminopropyl Triethoxysilane
General function
A silane that bonds to the hair surface, used in repair-positioned products to anchor a smoothing layer.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
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 suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
DependsCurls or waves needing flexible holdHow rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
- film former
- conditioning agent
-
4
Outer Tube: Paraffinum Liquidum/Mineral Oil
General function
The oil pressed from Outer Tube. How much weight a plant oil leaves depends on the hair it lands on; coarse hair tends to take more of it than fine hair.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- oil
- emollient
- ▾Below about here, the order stops meaning much. These are usually used at 1% or less.

Lactic Acid
· OUTER TUBE: Lactic Acid
General function
An acid used to set pH and, in scalp products, to loosen flakes.
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.
PubChemMay 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 hairA humectant moves water in whichever direction the air allows: it holds moisture in humid conditions and can pull it back out of hair in very dry ones.
- pH adjuster
- humectant
- exfoliant

Dipalmitoylethyl Hydroxyethylmonium Methosulfate
· OUTER TUBE: Dipalmitoylethyl Hydroxyethylmonium Methosulfate
General function
A biodegradable conditioning agent used for detangling in rich conditioners.
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.
PubChemMay 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.
May suitVery dry or highly damaged hairThe class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.
DependsBuild-up-sensitive routinesSubstantive by design. A routine with no detergent wash gives it nothing to leave with.
- conditioning agent

7
Cetyl Esters
· OUTER TUBE: Cetyl Esters
General function
A waxy ester blend that replaces spermaceti in creams. It thickens and leaves a smooth, non-greasy finish.
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 suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.
May suitFrizz-prone, damaged, or high-friction hairSpreads thin and lowers friction between strands without the heaviness of a fixed oil.
- light ester
- emollient
- thickener

Outer Tube: Cetrimonium Chloride
General function
A positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.

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. and 1 listing we don’t count, from grey-market or unverified sellers.
How we work this out
- 8.5 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 $36 is the price we have observed for the 8.5 oz. We need three stores before we call a price commonly seen.
- Good value under $23 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.66/oz; at 8.5 oz that is $23. 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 $31 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8.5 oz.

Formula score
10 of 10
The formula carries the systems a treatment is built around, and it sits in the middle of the range for masks and treatments 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 576 masks and treatments we’ve priced
- Covers 6 of the 6 things a treatment should do
- Reviewers mention 2 recurring complaints
- Rich emollientsThe depth a treatment step is built around.3 pts

- A humectantBinds water into the hair.1 pt
- A stated dwell timeThe brand says how long to leave it on.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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.

Claims check
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.

Reviewers
What people report
Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.
Many reviewers say their hair feels noticeably softer and smoother after a single use.
Reviewers across hair typesSome reviewers find the two-part tube hard to squeeze evenly, so getting the product out is a struggle.
Reviewers across hair typesSome reviewers say the current formula feels weaker than the older version they used before.
Reviewers who used the earlier formulaSeveral reviewers with dry, bleached, or damaged hair say it restored moisture, while others say it did nothing for them.
Reviewers with dry or damaged hairSeveral reviewers say the mask can feel heavy, greasy, or hard to rinse, while others find it light.

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.
- 6 sources consulted for this product (4 manufacturer or regulatory, 2 retailer, 0 editorial), last checked 2026-10-31.
- Ingredient references are linked for 3 of 7 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 2026-10-03.
