How much cleansing you need depends on how fast your scalp gets oily, how much product you layer and your water. The consultation works that out.

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: binding water is one of its main jobs.

Scalp active None

No over-the-counter scalp active.

Hard-water defence Chelators present

Contains chelators, which 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 Present

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 (39)

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 · Water/Aqua/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 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 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 not suitBuild-up-sensitive routines
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.

DependsVery dry or highly damaged hair
Among 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.

Indian Journal of Dermatology
- amphoteric cleanser
- secondary cleanser

3 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
4 Aloe Barbadensis Leaf Juice

General function
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.

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

May suitCurls or waves needing flexible hold
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

May suitFine or easily flattened hair
Hydration with no oil attached, so it adds very little weight even high on a list.

May suitVery dry or highly damaged hair
Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.
- humectant
- botanical extract
- gum
5 Glycerin

General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.

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.

6 Cocos Nucifera Liquid Endosperm
7 Sclerocarya Birrea (Marula) Seed Oil · Sclerocarya Birrea Seed Oil

General function
Marula oil - light, stable, used for shine and softness.

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
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

May suitFrizz-prone, damaged, or high-friction hair
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

May not suitFine or easily flattened hair
Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

- emollient
8 Rubus Fruticosus (Blackberry) Fruit Extract · Rubus Fruticosus Fruit Extract

General function
An extract from the fruit of Blackberry (Rubus Fruticosus). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

15 Butyrospermum Parkii (Shea) Butter · Butyrospermum Parkii Butter

General function
A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.

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
Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

May suitVery dry or highly damaged hair
A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

- emollient

16 Eugenia Caryophyllus Flower Oil
17 Citrus Aurantium Dulcis Peel Oil

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

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 not suitFragrance-sensitive routines
Essential 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.

18 Cocos Nucifera (Coconut) Oil · Cocos Nucifera 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.

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.

25 Levulinic Acid

General function
A plant-derived preservative usually paired with sodium levulinate.

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.

27 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.

May suitMaximum-hold styling
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
- conditioning agent
- polymer
- gum
28 Cocoglucosides Hydroxypropyltrimonium 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.

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 suitFrizz-prone, damaged, or high-friction hair
A 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 hair
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

DependsBuild-up-sensitive routines
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
- conditioning agent
29 Sodium Cocoyl Glutamate

General function
An amino-acid-derived cleanser, among the mildest in common use, with a low-foam, creamy feel.

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.

31 Betaine

General function
A sugar-beet derived humectant that binds water. Despite the name it is not a cleanser like cocamidopropyl betaine.

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
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
A 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.

32 Trisodium Ethylenediamine Disuccinate

General function
A readily biodegradable chelator used in place of EDTA to bind hard-water minerals.

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.

36 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.

37 Sodium Hydroxide

General function
A strong base used in trace amounts to raise pH; fully neutralised in the finished product.

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
The 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.

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.
Commonly seen is the middle half of current prices for the 8 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
Good value under $3 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.42/oz; at 8 oz that is $3. Under that line you are paying less than most of them.
About $9 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8 oz.

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.

Several reviewers specifically buy and use it together with the matching Simply Smoothing Conditioner as a paired routine rather than on its own.

reviewers describing their routine

Reviewers describe hair coming out noticeably smoother and shinier, holding up even in humid weather without frizzing.

general reviewers, one specifically on a humid day

A few reviewers with formaldehyde allergies or a history of scalp itchiness say the gentle formula lets them wash without a reaction.

reviewers who specifically mention allergies or past scalp irritation

Reviewers with fine or oily hair say it cleans without feeling heavy or greasy afterward.

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.

Ingredient references are linked for 11 of 22 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.
