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.
Nothing here is built to reduce combing force.
No oils or butters in the list.
Humectants near the top — water-binding is a headline mechanism here.
Nothing here needs a detergent wash to remove.
Chelators are present — they 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. 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 small humectant and solvent that keeps formulas stable and helps active ingredients spread.
Listed in the first three ingredients, it is likely a structural part of this formula.
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 solvent that helps dissolve ingredients that resist both oil and water, and improves how evenly they deposit.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
Keeps fragrance and oils dissolved in a watery formula so it stays clear.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 solubiliser that dissolves fragrance and oils into water so the product stays clear.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Roman chamomile extract, used at low levels for a soothing claim.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A light humectant and carrier that helps extracts dissolve.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

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 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.
A sugar-based humectant that adds moisture and a slight cushiony feel.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

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.
A soy- or sunflower-derived lipid that helps conditioning ingredients spread evenly on the strand.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
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.
Flaxseed gel. A natural polysaccharide that gives soft, flexible hold in curl products.
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 polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
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.
The smallest amino acid in hair protein, added for moisture binding.
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.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
A fermented sugar gum that thickens water-based formulas and adds soft, natural hold.
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 polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
A soothing ingredient used in scalp formulas.
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.
A protein broken into fragments small enough to cling to the hair. It fills gaps on damaged strands and firms the feel for a few washes; too much reads as stiff.
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.
An amino acid used in conditioning blends for moisture binding.
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.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
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.
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 rose-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 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.
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 · 1.7 oz
Priced above the products that do the same job. Stores sell it above the $5 line; products that do this job typically go for about $15 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 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.

Reviewers
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
A few reviewers report their dandruff got worse or the product made no noticeable difference after weeks of use.
Many reviewers with dry, flaky or itchy scalps say the drops relieve irritation without leaving hair oily or weighed down.
Several reviewers describe the dropper applicator as messy or hard to control, with liquid running out before it reaches the scalp.
