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.
A reset wash that removes oil, buildup, and most residue.
An ordinary shampoo lather.
Conditioning agents are present, lower in the list.
Humectants near the top: binding water is one of its main jobs.
No over-the-counter scalp active.
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.
Ingredients that matter
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.

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.
A mild cleanser that gives a creamy lather and leaves hair less stripped than sulfates.
Listed in the first three ingredients, it is likely a structural part of this formula.
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Listed in the first three ingredients, it is likely a structural part of this formula.
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 mild cleanser that keeps foaming in hard water and rinses cleanly.
Listed in the first three ingredients, it is likely a structural part of this formula.
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
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 positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Castor oil hardened into a wax. It thickens balms and gives a firm, sealing 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.
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
Forms a physical barrier on the strand that slows water leaving it. Nothing else in a formula holds moisture in as bluntly.
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.
An amaranth seed extract used at low levels for moisture and shine 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.
A food-grade preservative that works only in acidic formulas, which is why it usually appears alongside citric acid.
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 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.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Holds hard-water minerals in solution so they rinse away instead of depositing on the 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.
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.
A light, widely used oil that softens without much weight.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
Produces a cooling, medicinal sensation on the scalp and contributes scent.
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 floral fragrance component listed separately as a recognised contact allergen.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A lavender-like fragrance component, related to linalool and listed for the same allergen reason.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A pine-scented component of essential oils, declared as part of the fragrance.
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.
The main scent compound in vanilla, used as a fragrance note.

Priced above the products that do the same job. Stores sell it above the $12 line; products that do this job typically go for about $14 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 carries what a shampoo is built around, and 2 products we score as close matches cost at least a quarter less per ounce. The difference is the label, not 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.

Claims check
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.
