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.
Conditioning agents sit high in the list — this is a detangling formula.
No oils or butters in the list.
Middle of the range — noticeable on fine hair, light on coarse hair.
Humectants appear, but low enough to be a minor part.
No protein or amino acids in the list.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No chelating agent 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.

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 fatty alcohol used to thicken creams and add slip. It softens rather than dries.
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 gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much build-up.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
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.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
An amino acid used for moisture binding and to bring the formula to an acidic pH.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
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.
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.
Cornmint oil, used for a cooling sensation and mint 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.
Peppermint essential oil, used for scent and the cooling feeling on the scalp.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.
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 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 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 jasmine-like fragrance component named separately as a recognised 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 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 rose-scented fragrance component, listed on its own 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 cellulose thickener used for body and slip.
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.
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.
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness 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.
It hydrates without adding oil or a film, which is the combination fine hair usually needs.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.
A soy- or sunflower-derived lipid that helps conditioning ingredients spread evenly on the strand.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A solvent that helps dissolve ingredients that resist both oil and water, and improves how evenly they deposit.
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 starch fragment that soaks up oil and water, which is what puts it in dry shampoos. It also carries spray-dried plant extracts and leaves a light film.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Takes up oil at the root, which is where fine hair goes flat first.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
A simple sugar used as a light humectant.
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.
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.
An acid used to set pH and, in scalp products, to loosen flakes.
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 vitamin B5 salt, related to panthenol and used for moisture 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.
It hydrates without adding oil or a film, which is the combination fine hair usually needs.

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 fruit acid used to set an acidic pH; at higher levels it also loosens surface build-up.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.
A colour added to tint the product itself. It does not colour 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.
A violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.
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.

Reviewers
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
Reviewers report noticeably less hair shedding/fall and thicker-feeling hair within days to a few weeks of regular use
used as part of the full Scalp Recovery system, applied roughly 1-2x/weekA little product goes a long way -- reviewers note only a pea-sized amount is needed per use, making the bottle last a long time
general reviewer baseSome reviewers using the conditioner alongside the Nioxin nighttime scalp serum report visibly reduced hair fall within just a few days
reviewers combining the conditioner with other Nioxin scalp-recovery productsA subset of reviewers, including one citing a thyroid condition, report the product still leaves the scalp dry/drying and hair breaking despite weekly use
reviewers with pre-existing dryness/breakage issuesStrong minty/menthol scent from the peppermint and cornmint oils is called out repeatedly, both as a liked cooling sensation and as an off-putting fragrance
