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 Moderate

Removes oil and product; leaves some conditioning behind.

Expected lather Moderate

An ordinary shampoo lather.

Slip and detangling Moderate

Conditioning agents are present, lower in the list.

Water-binding (humectants) High

Humectants near the top — water-binding is a headline mechanism here.

Scalp active None

No over-the-counter scalp active.

Hard-water defence Chelators present

Chelators are present — they bind hard-water and pool minerals.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Protein None

No protein or amino acids in the list.

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. These 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 (34)

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 · 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 ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
- solvent
2 Sodium Lauroyl Methyl Isethionate

General function
A gentle, dense-lathering cleanser used as the primary detergent in many sulfate-free shampoos.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitCurls or waves needing flexible hold
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.

May suitDry, coarse, or high-porosity hair
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.

May suitVery dry or highly damaged hair
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
- mild anionic cleanser
- cleanser
3 Heptyl Glucoside

General function
A very mild sugar-derived cleanser used in low-foam formulas.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitDry, coarse, or high-porosity hair
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

May suitVery dry or highly damaged hair
A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.

May not suitBuild-up-sensitive routines
Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.

PubChem
- nonionic cleanser
- cleanser
4 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.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitDry, coarse, or high-porosity hair
High-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 hair
Binds 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 hair
Water 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.

Scientific Reports
- humectant
5 Cocamidopropylamine Oxide

General function
A foam booster and mild cleanser that thickens the formula.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitDry, coarse, or high-porosity hair
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

May suitVery dry or highly damaged hair
One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

May not suitBuild-up-sensitive routines
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
- amphoteric cleanser
- secondary cleanser
- cleanser
6 Pca Glyceryl Oleate

General function
A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- light ester
- emollient
7 Acrylates Copolymer

General function
A hold polymer that forms a firm, humidity-resistant film. It is the usual source of a hard cast in gels.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitClimate-sensitive or frizz-prone hair
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

May suitMaximum-hold styling
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

DependsBuild-up-sensitive routines
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
- film former
- polymer
▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
8 Triethyl Citrate

General function
A citrate ester used to stabilise fragrance and support the preservative system.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

DependsFrizz-prone, damaged, or high-friction hair
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

General function
Cedarwood essential oil, used as a woody fragrance note.

It 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 routines

11 Elettaria Cardamomum Seed Oil

General function
The essential oil of Elettaria Cardamomum. Essential oils are aromatic — they are in the formula for scent, and they are a common source of declared fragrance allergens.

12 Cistus Ladaniferus Resin
13 Daucus Carota Sativa (Carrot) Seed Oil

General function
The oil pressed from Daucus Carota. 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.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitDry, coarse, or high-porosity hair
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

May suitVery dry or highly damaged hair
Humectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.

28 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.

Estimated lower-concentration zone
It 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 hold
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

May suitFrizz-prone, damaged, or high-friction hair
Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
Binds 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 hair
Copper 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.

PubChem

34 Citric Acid · 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 zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

May suitFrizz-prone, damaged, or high-friction hair
The 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 hair
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

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

10 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.
Commonly seen is the middle half of current prices for the 10 oz at recognised stores — the cheapest quarter and the dearest quarter are left out, so one sale or one overpriced listing can’t move it.
Good value under $12 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.17/oz; at 10 oz that is $12. Under that line you are paying less than most of them.
About $18 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 10 oz.

Final decision

Should you buy it?

Good for the right person, not the lowest cost

Best user

People sensitive to fragrance who want a formula with no added fragrance and washing without sulfates

Biggest tradeoff

Not ideal for anyone sensitive to fragrance, soft, over-stretchy hair that needs protein, or very dry or very humid climates

Claims check

What the brand says, against what the formula shows

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

Reviewers

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.

Earthy scent is called out favorably

Reviewers in hard-water areas say the scalp feels genuinely clean, especially when paired with the brand's hard-water treatment packets

reviewers dealing with hard water

Fine-hair reviewers report it cleans thoroughly without leaving hair feeling brittle or stripped

reviewers with fine hair

A reviewer felt it made no noticeable difference for their hair/water situation

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.
3 sources consulted for this product (3 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-25.
Ingredient references are linked for 8 of 25 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.
