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.
Oils are present, but low enough to be a finishing touch.
Middle of the range — noticeable on fine hair, light on coarse hair.
Protein appears, low enough to be a supporting ingredient.
Humectants in the working part of the formula.
Conditioning agents sit high in the list — this is a detangling formula.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
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.

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 fatty alcohol that thickens conditioners and helps them coat the hair evenly.
Listed in the first three ingredients, it is likely a structural part of this formula.
The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.
A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.
Listed in the first three ingredients, it is likely a structural part of this formula.
Electrokinetic measurement puts the C22 quat ahead of the C16 ones for deposition: the longer chain adds van der Waals stabilisation on top of the charge binding. That extra deposit is what coarse hair usually needs to comb through.
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
A fatty alcohol used to thicken creams and add slip. It softens rather than dries.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.
A fast-evaporating alcohol used as a solvent and to speed drying. Well down the list it is a processing aid; near the top it can leave hair feeling dry.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
Porous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
It evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.
A preservative and solvent that also occurs naturally in some essential oils.
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 most common modern preservative; it keeps the product free of bacteria and mould. It sits well below 1% of the formula.
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 small humectant and solvent that keeps formulas stable and helps active ingredients spread.
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 conditioning silicone with a positive charge, so it deposits where hair is damaged and stays through rinsing.
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.
Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
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.
Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.
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.
Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.
A light protein used for slip and shine rather than strength.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
Kukui nut oil - a light oil used for softness on fine textured hair.
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.

Formula
Nothing separates this from the middle of the range for masks and treatments, on formula or on cost per ounce.
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, for less
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.

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.
Defends against breakage
Protein or ceramides are present, but low enough that this reads as support, not treatment.
Supports the surface, not a treatment.
We look at the first 10–15 ingredients and what they do in a formula — not marketing. If the list doesn't speak to a claim, we don't assume.
