What the formula actually does
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 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 listed; it sits below the working ingredients.
Ingredients that matter
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.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| Water | solvent | The base everything else is dissolved in | Neutral |
| Sodium Laureth Sulfate | sulfate cleanser | — | Cleanses |
| Sodium Lauryl Sulfate | sulfate cleanser | — | Cleanses |
| Cocamidopropyl Betaine | amphoteric cleanser | — | Cleanses |
| Zinc PyrithionePyrithione Zinc | active | The over-the-counter active | Active |
| Sodium Xylenesulfonate | solubilizer | Keeps oils dissolved in water | Stabilizes |
| Zinc Carbonate | mineral | Adds texture or opacity | Neutral |
| Glycol Distearate | opacifier | Makes the product look creamy | Softens |
| Fragrance | fragrance | The scent | Fragrance |
| Dimethiconol | silicone | A little smoothing and shine | Buildup |
| Sodium Benzoate | preservative | Keeps the product from spoiling | Stabilizes |
| Dimethicone | silicone | A little smoothing and shine | Buildup |
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.
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Listed in the first three ingredients, it is likely a structural part of this formula.
A strong, high-foaming cleanser and the most common shampoo detergent. It removes oil and product efficiently, which can be more than dry or colour-treated hair wants.
Listed in the first three ingredients, it is likely a structural part of this formula.
A sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.
Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.
Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.
A high-foaming, strongly cleansing detergent. It clears build-up thoroughly and is the harsher of the two common sulfates.

Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.
Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
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.
An over-the-counter anti-dandruff active that reduces the yeast associated with flaking. Its percentage is stated in the drug facts panel.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A hydrotrope that keeps a shampoo clear and pourable.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A zinc salt that accompanies zinc pyrithione in some anti-dandruff formulas.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A wax that gives shampoo its pearly look and a slightly richer feel.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
A high-shine silicone often paired with dimethicone for a smoother, glossier finish.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
A strong detergent used mainly in clarifying and deep-cleansing shampoos.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Cleansing is what lifts deposited films off the strand. How completely depends on which detergent it is and how high on the list it sits.
Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
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.
A light humectant and carrier that helps extracts dissolve.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Light and water-binding rather than oily, so it hydrates without contributing weight.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
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.
A humectant that also helps preserve the formula, often used where a brand wants a short preservative list.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

Vitamin B3, used in scalp products for conditioning claims.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
This product is an over-the-counter drug as well as a cosmetic. It treats a cosmetic scalp condition; it does not diagnose or treat disease.

Price · 12.5 oz
Usually a good value. Most stores sell it under the $7 line, and products that do this job typically go for about $7 at this size.
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.
Formula
The formula covers the core of what a shampoo does, and it costs less per ounce than most shampoos in our library.
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
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.

Final decision
Flaking scalps who want an over-the-counter scalp active and a protein-free formula
Less suited to anyone sensitive to fragrance, sulfate-free routines and fresh keratin treatments, or curly-method routines
Nothing in our library matches it closely at a lower price.

Claims check
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.
