What the formula actually does

Read from the label, not the marketing

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 and butters None

No oils or butters in the list.

Weight on the hair Medium

Middle of the range — noticeable on fine hair, light on coarse hair.

Protein Minor

Protein appears, low enough to be a supporting ingredient.

Water-binding (humectants) High

Humectants near the top — water-binding is a headline mechanism here.

Slip and detangling High

Conditioning agents sit high in the list — this is a detangling formula.

Time on the hair 5–30 min

A long treatment window — plan the time before you start.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Ingredients that matter

The ingredients that change a decision

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.

Full ingredient list (24)

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.

1 Water · Water/Aqua/Eau

General function
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
- solvent
2 Stearyl Alcohol

General function
A fatty alcohol that thickens conditioners and helps them coat the hair evenly.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitDry, coarse, or high-porosity hair
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.

May suitFrizz-prone, damaged, or high-friction hair
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

DependsFine or easily flattened hair
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.

PubChem
- fatty alcohol
- emollient
- thickener
3 Squalane

General function
The fully hydrogenated form of squalene, now made from olive or sugarcane rather than shark liver. Hydrogenation is what makes it so slow to oxidise; it spreads very lightly and absorbs without a greasy film.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitFrizz-prone, damaged, or high-friction hair
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

PubChem
- emollient
- conditioning agent
4 Glycerin

General function
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.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitDry, coarse, or high-porosity hair
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.

May suitVery dry or highly damaged hair
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.

DependsClimate-sensitive or frizz-prone hair
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.

Scientific Reports
- humectant
5 Cetyl Alcohol

General function
A fatty alcohol used to thicken creams and add slip. It softens rather than dries.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitDry, coarse, or high-porosity hair
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.

May suitFrizz-prone, damaged, or high-friction hair
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.

PubChem

6 Triolein

General function
The main triglyceride in olive oil, used as a rich softening emollient.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitFine or easily flattened hair
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

May suitFrizz-prone, damaged, or high-friction hair
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
- light ester
- emollient
7 C13-15 Alkane

General function
A plant-derived light alkane used as a clean-feeling replacement for silicone or mineral oil.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitFrizz-prone, damaged, or high-friction hair
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
- emollient
- solvent
8 Brassicamidopropyl Dimethylamine

General function
A plant-derived conditioning agent that smooths the cuticle and eases combing.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitFrizz-prone, damaged, or high-friction hair
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

May suitVery dry or highly damaged hair
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

DependsBuild-up-sensitive routines
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
- conditioning agent
▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
9 Ethylhexylglycerin

General function
A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

10 Tocopherol

11 Aspartic Acid

General function
An amino acid used for moisture binding and to help set an acidic pH.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitVery dry or highly damaged hair
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

DependsFrizz-prone, damaged, or high-friction hair
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.

DependsProtein-sensitive hair
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

12 Cetearyl Olivate
- emollient
- light ester
13 Salvia Hispanica Seed Extract

14 Yeast Amino Acids

General function
An amino acid of the kind hair protein is built from. Small enough to sit inside the cuticle, and used for water binding rather than strength.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitVery dry or highly damaged hair
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

DependsClimate-sensitive or frizz-prone hair
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.

DependsProtein-sensitive hair
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

17 Panthanol
18 Sodium Gluconate

General function
A gentle, biodegradable chelator that binds hard-water minerals in place of EDTA.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.

May suitGray, silver, or brass-prone hair
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.

PubChem
- hard-water chelator
19 Fragrance · Fragrance/Parfum

General function
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.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May not suitFragrance-sensitive routines
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

20 Linalool

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.

How we work this out

8 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
Commonly seen is the middle half of current prices for the 8 oz at recognised stores — the cheapest quarter and the dearest quarter are left out, so one sale or one overpriced listing can’t move it.
Good value under $16 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.01/oz; at 8 oz that is $16. Under that line you are paying less than most of them.
About $34 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 8 oz.

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

What the brand says, against what the formula shows

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

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.

Users with fine or thinner hair often say the texture feels light and does not weigh hair down.

Walmart reviewers with fine/thin hair

Reviewers commonly report softer, smoother hair and improved detangling after a five- to ten-minute use.

Walmart reviewers across straight, wavy, and curly hair

Some reviewers with curlier hair find it insufficiently hydrating, while others say too much can leave hair greasy.

Walmart reviewers with curly hair or oil-prone results

How this page was made

Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per product.
The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
4 sources consulted for this product (3 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
Ingredient references are linked for 10 of 16 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
