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
Moderate
An ordinary shampoo lather.
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
Chelators present
Chelators are present — they bind hard-water and pool minerals.
Needs detergent to remove
Yes
Water-insoluble silicones or waxes: a detergent wash is what removes them.

What the list leaves out, and what it carriesNo sulfates or drying alcohols. Protein-free: this is built for moisture rather than for strengthening. Contains fragrance. The silicones here need a detergent wash to come off.

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.

A gentle, dense-lathering cleanser used as the primary detergent in many sulfate-free shampoos.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.

Dimethicone
General function
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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFrizz-prone, damaged, or high-friction hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

Acrylates Copolymer
General function
A hold polymer that forms a firm, humidity-resistant film. It is the usual source of a hard cast in gels.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitClimate-sensitive or frizz-prone hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
May suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

Polyglyceryl-3 Laurate
General function
A plant-derived polyglycerol ester. It emulsifies without ethoxylation, which is why it turns up in formulas positioned as PEG-free, and leaves a soft feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Propanediol
General function
A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it hydrates without contributing weight.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

Acetic Acid
General function
Vinegar acid, used in tiny amounts to bring the formula to an acidic pH so the cuticle lies flat.

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.

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
- 8.5 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 $34 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 $10 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.17/oz; at 8.5 oz that is $10. Under that line you are paying less than most of them.
- About $18 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 8.5 oz.

Formula score
9 of 10
The formula carries what a shampoo is built around, and 6 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.
How the score is counted
- 6 products we score as doing the same job cost less per ounce
- Costs more per ounce than 85% of the 805 shampoos we’ve priced
- Covers 6 of the 7 things a shampoo should do
- Reviewers mention 4 things they like about how it performs
- A working detergent systemWhat actually removes oil and product.3 pts
- Slip for detanglingReduces the force it takes to comb wet hair.2 pts
- A humectantBinds water into the hair.1 pt
- A hard-water chelatorBinds the minerals that dull hair in hard water.1 pt
- A pH adjusterBrings the formula to the acidic pH hair prefers.1 pt
- No detergent-dependent filmNothing that needs a clarifying wash to remove.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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.

We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.
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.

How to read this
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.

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.
- 6 sources consulted for this product (4 manufacturer or regulatory, 2 retailer, 0 editorial), last checked 2026-08-25.
- Ingredient references are linked for 26 of 43 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.
- Formula readings: derivation v22. Record last updated 2026-08-25.
