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 and product; leaves some conditioning behind.
Thick foam that spreads quickly through the hair.
Some slip, mostly from esters or silicones rather than conditioners.
Humectants appear, but low enough to be a minor part.
Carries an over-the-counter scalp active, listed under Drug Facts.
No chelating agent in the list.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No protein or amino acids in the list.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Full ingredient list (21)
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.

Zinc Pyrithione
· Pyrithione Zinc (1%)
General function
An over-the-counter anti-dandruff active that reduces the yeast associated with flaking. Its percentage is stated in the drug facts panel.
Leading ingredientPubChemListed in the first three ingredients, it is likely a structural part of this formula.

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.

Sodium Lauryl Sulfate
General function
A high-foaming, strongly cleansing detergent. It clears build-up thoroughly and is the harsher of the two common sulfates.
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.

Glycol Distearate
General function
A wax that gives shampoo its pearly look and a slightly richer feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Fragrance
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.

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.
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.
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 Xylenesulfonate

Dimethicone
General function
The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.
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 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 hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

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

Butylene Glycol

A light humectant and carrier that helps extracts dissolve.
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 hairLight and water-binding rather than oily, so it adds less weight than oils or butters do.

How we work this out
- 12.5 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 $8.99 is the price we have observed for the 12.5 oz. We need three stores before we call a price commonly seen.
- Good value under $6 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.47/oz; at 12.5 oz that is $6. Under that line you are paying less than most of them.
- About $7 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 12.5 oz.
Formula
Low cost per ounce, with a short formula: there is no slip for detangling here, and that is a system most shampoos carry.
How the score is counted
- 4 products that do the same job cost less per ounce
- Costs less per ounce than 78% of the 1544 shampoos we’ve priced
- No slip for detangling in the formula

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.
- 4 sources consulted for this product (1 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-10.
- Ingredient references are linked for 7 of 9 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 2026-10-11.
