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.
Removes oil, buildup, and most residue — a reset wash.
Thick foam that spreads quickly through the hair.
Conditioning agents are present, lower in the list.
Humectants in the working part of the formula.
No over-the-counter scalp active.
Chelators are present — they bind hard-water and pool minerals.
Nothing here needs a detergent wash to remove.
No protein or amino acids in the list.
Fragrance sits in the first eight ingredients — a larger share of the formula.

Full ingredient list (17)
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

1
Water
· 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

Sodium C14-16 Olefin Sulfonate
General function
A strong non-sulfate detergent used in "sulfate-free" shampoos. It cleans about as thoroughly as a sulfate despite the label difference.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitBuild-up-sensitive routinesA strong detergent with no sulfate on the label. It removes deposited films about as completely as a sulfate does.
May not suitVery dry or highly damaged hairSulfate-free on the label is a naming fact, not a mildness one: this is an efficient detergent, and hair short of moisture can feel it.

Cocamidopropyl Betaine
General function
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Indian Journal of DermatologyMay suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May not suitBuild-up-sensitive routinesThe mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
DependsVery dry or highly damaged hairAmong the mildest detergents in use — it is what baby shampoos are built on — but it is almost always the second detergent in a formula. How much a wash strips is still decided by the primary detergent listed above it.

Sodium Chloride
General function
Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.
Supporting ingredientPubChemListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- salt
- thickener
- ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.

Sodium Gluconate
General function
A gentle, biodegradable chelator that binds hard-water minerals in place of EDTA.
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 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.
- hard-water chelator

Glycerin
General function
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
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.
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.

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.
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.

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-10
General function
A cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.
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.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Disodium EDTA
General function
Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.

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
- 13.5 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 $54.95 is the price we have observed for the 13.5 oz. We need three stores before we call a price commonly seen.
- Good value under $17 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.25/oz; at 13.5 oz that is $17. Under that line you are paying less than most of them.
- About $31 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 13.5 oz.
Formula
This is a complete shampoo formula. It is also above the range for shampoos per ounce, with 6 close matches selling for meaningfully less.
How the score is counted
- 6 products that do the same job cost less per ounce
- Costs more per ounce than 87% of the 817 shampoos we’ve priced
- Covers 6 of the 7 things a shampoo should do
- Reviewers mention 4 things they like about how it performs

The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

How this page was made
- Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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 10 of 12 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
- We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
- 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 v22. Record last updated 2026-08-25.
