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.
Some slip, mostly from esters or silicones rather than conditioners.
No oils or butters in the list.
Water-first and light: unlikely to flatten fine hair.
Humectants in the working part of the formula.
No protein or amino acids in the list.
Nothing here needs a detergent wash to remove.
Contains chelators, which bind hard-water and pool minerals.
Fragrance is listed; it sits below the working ingredients.
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.
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 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.
A mild co-cleanser that keeps foam stable in hard water.
Listed in the first three ingredients, it is likely a structural part of this formula.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A mild cleanser that gives a creamy lather and leaves hair less stripped than sulfates.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

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.
A very mild cleanser that softens the effect of stronger detergents.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
An oil-soluble acid that loosens flakes and clears build-up around the follicle. In dandruff shampoos it appears in the drug facts panel with a stated percentage.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
An amino-sugar derivative used for its hair-conditioning and antistatic properties in scalp serums and treatment masks.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A zinc salt of a natural moisturising factor, used on the scalp for oil-control and soothing claims.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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.
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.
Produces the cooling, tingling feeling on the scalp. The sensation is real; it is not evidence that anything else is happening.
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 gentler cooling agent than menthol, with less 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.
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 strong base used in trace amounts to raise pH; fully neutralised in the finished product.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
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 citrus-smelling fragrance component that EU rules require to be named separately because some people react to 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.
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 floral fragrance component listed separately as a recognised contact allergen.

A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

Price · 5 oz
Good value on sale. Some stores sell it under the $46 line; products that do this job typically go for about $78 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
It costs about what other scalp treatments cost per ounce, but the formula leaves out conditioning agents up front, which most of the format carries.
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.
