Hair that needs proteinthere is none in this list
Hair that tangles wetnothing here makes combing easier

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 Strong

A reset wash that removes oil, buildup, and most residue.

Expected lather High

Thick foam that spreads quickly through the hair.

Slip and detangling Little

Nothing here is built to reduce combing force.

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 None

No chelating agent in the list.

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. 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 (7)

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
    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 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 ingredient

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

    May suitBuild-up-sensitive routines

    A 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 hair

    Sulfate-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.

    PubChem
    • olefin sulfonate cleanser
    • cleanser
  • 3 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
    • cleanser
  • 4 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.

    Scientific Reports
    • humectant
  • 5 Propylene Glycol
    General function

    A small humectant and solvent that keeps formulas stable and helps active ingredients spread.

    Supporting ingredient

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

    May suitFine or easily flattened hair

    Light and water-binding rather than oily, so it adds less weight than oils or butters do.

    May suitVery dry or highly damaged hair

    A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

    DependsClimate-sensitive or frizz-prone hair

    A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

    PubChem
    • humectant
    • solvent
  • 6 Disodium Cocoamphodipropionate
    General function

    A very mild cleanser used in baby and sensitive-scalp shampoos.

    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.

    PubChem
    • amphoteric cleanser
    • secondary cleanser
    • cleanser
  • 7 PEG-150 Distearate
    General function

    A thickener that gives shampoo and body wash their pourable, slightly gel-like texture.

    Supporting ingredient

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

    • thickener
    • emulsifier

What the whole list adds up to

  • 3 cleansers
  • 2 solvents
  • 2 amphoteric cleansers
  • 2 secondary cleansers
  • 2 humectants
  • 1 olefin sulfonate cleanser
  • 1 thickener

Where we’ve seen it6 listings · 5 stores

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
  1. 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.
  2. 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.
  3. Good value under $9 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.11/oz; at 8 oz that is $9. Under that line you are paying less than most of them.
  4. About $22 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8 oz.

Formula

Formula score
6 of 10

Both the formula and the price land mid-range: it covers the core of what a shampoo does and costs about what shampoos cost 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 61% of the 1544 shampoos we’ve priced
  • No slip for detangling in the formula
  • Reviewers mention 3 things they like about how it performs
  • A working detergent systemWhat actually removes oil and product.3 pts

  • A pH adjusterBrings the formula to the acidic pH hair prefers.1 pt
  • No detergent-dependent filmNothing that needs a clarifying wash to remove.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.

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, 1 retailer, 2 editorial), last checked 2026-10-31.
  • Ingredient references are linked for 5 of 5 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 2026-10-07.
