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.
No oils or butters in the list.
Water-first and light: unlikely to flatten fine hair.
No protein or amino acids in the list.
Humectants in the working part of the formula.
Conditioning agents are present, lower 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 (29)
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.

Water
· AQUA / 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
Sodium Laureth Sulfate
General function
A strong, high-foaming cleanser and the most common shampoo detergent. It removes oil and product efficiently, which can be more than dry or colour-treated hair wants.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Indian Journal of DermatologyMay suitBuild-up-sensitive routinesA sulfate detergent can lift deposited silicone, wax and styling films, which is what resets a routine before build-up is visible.
May suitFine or easily flattened hairFine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.
May not suitDry, coarse, or high-porosity hairCoarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.

Coco-Betaine
General function
A coconut-derived mild cleanser that boosts foam and softens stronger detergents.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May suitVery dry or highly damaged hairOne of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

Sodium Chloride
· SODIUMCHLORIDE

Laureth-5 Carboxylic Acid
General function
A mild cleanser used to soften a detergent base.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitBuild-up-sensitive routinesCleansing is what lifts deposited films off the strand. How completely depends on which detergent it is and how high on the list it sits.

Cocamide MIPA
General function
A coconut-derived thickener that stabilises shampoo foam and gives the liquid its body.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May suitVery dry or highly damaged hairA sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.

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.
International Journal of TrichologyMay suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFrizz-prone, damaged, or high-friction hairAmino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Sodium Benzoate
General function
A food-grade preservative that works only in acidic formulas, which is why it usually appears alongside citric acid.

Sodium Hydroxide
General function
A strong base used in trace amounts to raise pH; fully neutralised in the finished product.
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 TrichologyDependsFrizz-prone, damaged, or high-friction hairThe alkali half of a pH-adjusting pair, used in small amounts to bring a formula up to its target rather than to make it alkaline. Alkaline conditions raise the fibre's surface charge and lift the scales — but the finished pH is not on the label.
- pH adjuster
-
10
Citric Acid
General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.
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 TrichologyMay suitBuild-up-sensitive routinesHolds hard-water minerals in solution so they rinse away instead of depositing on the hair.
May suitFrizz-prone, damaged, or high-friction hairThe acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.
May suitGray, silver, or brass-prone hairWhere a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

Polyquaternium-7
General function
A conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.
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.

Panthenol
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 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 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.

2-Oleamido-1,3-Octadecanediol
General function
A ceramide-like lipid used to reinforce the outer surface of damaged hair.
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 hairRestoring surface lipids lowers friction between strands, which is where much of the roughness in damaged hair comes from.
May suitProtein-sensitive hairA lipid, not a protein, despite sitting alongside proteins in most repair claims. It does not carry the stiffening effect.
May suitVery dry or highly damaged hairCeramides are the lipid class bleaching and heat deplete. Replacing them works on the surface layer rather than adding protein stiffness.

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
- 8.4 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 $48 is the price we have observed for the 8.4 oz. We need three stores before we call a price commonly seen.
- Good value under $52 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $6.23/oz; at 8.4 oz that is $52. Under that line you are paying less than most of them.
- About $68 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8.4 oz.
Formula
Above the range for masks and treatments per ounce for a shorter formula: there is no rich emollients in the list.
How the score is counted
- Nothing in our library does the same job for less
- Costs more per ounce than 76% of the 576 masks and treatments we’ve priced
- No rich emollients in the formula
- No conditioning agents up front either

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.

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.
- 3 sources consulted for this product (0 manufacturer or regulatory, 0 retailer, 3 editorial), last checked 2026-10-17.
- Ingredient references are linked for 9 of 17 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 2026-10-17.
