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.

Cleansing strength Strong

Removes oil, buildup, and most residue — a reset wash.

Expected lather High

Thick foam that spreads quickly through the hair.

Slip and detangling Moderate

Conditioning agents are present, lower in the list.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Scalp active None

No over-the-counter scalp active.

Hard-water defence None

No chelating agent in the list.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Protein None

No protein or amino acids in the list.

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 (27)

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 · Aqua/Water

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 Sodium Laureth Sulfate

General function
A strong, high-foaming cleanser and the most common shampoo detergent. It removes oil and product efficiently, which can be more than dry or colour-treated hair wants.

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

May suitBuild-up-sensitive routines
A sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.

May suitFine or easily flattened hair
Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.

May not suitDry, coarse, or high-porosity hair
Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.

Indian Journal of Dermatology
- sulfate cleanser
- cleanser
3 Citric Acid

General function
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.

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

May suitBuild-up-sensitive routines
Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

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

May suitGray, silver, or brass-prone hair
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

International Journal of Trichology
- pH adjuster
- hard-water chelator
4 Cocamidopropyl Betaine

General function
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.

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
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

May not suitBuild-up-sensitive routines
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.

DependsVery dry or highly damaged hair
Among the mildest detergents in use — it is what baby shampoos are built on — but it is almost always the second detergent in a formula. How much a wash strips is still decided by the primary detergent listed above it.

▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
5 Sodium Hydroxide

General function
A strong base used in trace amounts to raise pH; fully neutralised in the finished product.

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.

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

International Journal of Trichology
- pH adjuster
6 Propylene Glycol

General function
A small humectant and solvent that keeps formulas stable and helps active ingredients spread.

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 suitFine or easily flattened hair
Light and water-binding rather than oily, so it hydrates without contributing weight.

May suitVery dry or highly damaged hair
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

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.

PubChem
- humectant
- solvent
7 Sodium Chloride

General function
Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.

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.
PubChem
- salt
- thickener
8 Sodium Benzoate

General function
A food-grade preservative that works only in acidic formulas, which is why it usually appears alongside citric acid.

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.
PubChem
- preservative
9 Hexylene Glycol

General function
A solvent that keeps other ingredients dissolved and helps preservatives work.

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 suitFine or easily flattened hair
Light and water-binding rather than oily, so it hydrates without contributing weight.

May suitVery dry or highly damaged hair
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

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.

PubChem

10 Polyquaternium-10

General function
A cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.

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 suitCurls or waves needing flexible hold
Cationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.

May suitFrizz-prone, damaged, or high-friction hair
A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

11 Salicylic Acid

12 Limonene

General function
A citrus-smelling fragrance component that EU rules require to be named separately because some people react to 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
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.

14 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.

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 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.

General function
A fermented sugar gum that thickens water-based formulas and adds soft, natural hold.

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 suitCurls or waves needing flexible hold
A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.

May suitFrizz-prone, damaged, or high-friction hair
A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.

May not suitMaximum-hold styling
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.

How we work this out

8.5 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.
Seen at $38.73 is the price we have observed for the 8.5 oz. We need three stores before we call a price commonly seen.
Good value under $15 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.74/oz; at 8.5 oz that is $15. Under that line you are paying less than most of them.
About $19 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 8.5 oz.

Final decision

Should you buy it?

Hard to justify at this price

Best user

Hair that stiffens on protein — for a protein-free formula and a proper reset wash

Biggest tradeoff

Not ideal for anyone sensitive to fragrance, sulfate-free routines and fresh keratin treatments, or dry or damaged hair

Best alternative if not

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.

Many reviewers report visible reduction in hair fall/breakage and some new regrowth over months of use, with a lightweight feel that does not weigh down fine hair.

multiple reviewers, fine-hair and hair-loss-concern users

Reviewers frequently praise a pleasant fragrance and added shine after use.

A vocal minority describe severe adverse effects, including large amounts of shedding by the handful and a reported loss of about a third of hair volume over months.

reviewers with sensitive scalps or reactive hair

Some reviewers report scalp irritation, dryness, and itchiness, which they attribute to the strong fragrance/chemical composition.

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 16 of 19 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.
