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
Light
Water-first and light: unlikely to flatten fine hair.
Protein
None
No protein or amino acids in the list.
Water-binding (humectants)
None found
No humectants, so nothing here pulls water into the hair.
Slip and detangling
High
Conditioning agents sit high in the list, so this is a detangling formula.
Needs detergent to remove
No
Nothing here needs a detergent wash to remove.

Ingredients that matter
The ingredients that change a decision
The workhorse ingredients, plus anything lower down that changes a decision. The chips name what an ingredient does. They are not safety scores, and no ingredient here is rated good or bad on its own.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| Sodium Bicarbonate | pH adjuster | Brings the formula to hair-friendly pH | pH balancer |
| Citric Acid | pH adjuster | Brings the formula to hair-friendly pH | pH balancer |
| Hydroxyethylcellulose | gum | Natural hold and clump definition | Holds |
| Ascorbyl Glucoside | antioxidant | Protects the formula | Stabilizes |
| Hydroxypropyl Guar Hydroxypropyltrimonium Chloride | conditioning agent | Adds slip, lower in the list | Detangles |
| PVP | film former | A supporting film former | Holds |
| Disodium Phosphate | pH adjuster | Fine-tunes the pH | pH balancer |
| Sodium Phosphate | pH adjuster | Fine-tunes the pH | pH balancer |
What the list leaves out, and what it carriesNo sulfates, silicones, or drying alcohols. Protein-free: this is built for moisture rather than for strengthening.
Full ingredient list (9)
In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.
-
1
Sodium Bicarbonate
General function
Baking soda. Used in trace amounts to raise pH; at higher levels it is alkaline enough to swell the cuticle.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitFine or easily flattened hairTakes up oil at the root, which is where fine hair goes flat first.
DependsFrizz-prone, damaged, or high-friction hairpH 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.
- pH adjuster
- absorbent
-
2
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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
International Journal of TrichologyMay suitBuild-up-sensitive routinesHolds hard-water minerals in solution so they rinse away instead of depositing on the hair.
May suitFrizz-prone, damaged, or high-friction hairThe 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 hairWhere a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.
- pH adjuster
- hard-water chelator

3
Hydroxyethylcellulose
General function
A cellulose thickener that gives gels and conditioners their body and adds a soft, flexible film.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitCurls or waves needing flexible holdA 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 hairA soft film binds neighbouring strands together, which is most of what helps flyaways lie down.
May not suitMaximum-hold stylingGum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
- gum
- thickener
- film former
- ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
-
4
Ascorbyl Glucoside
General function
A stable vitamin C derivative used as an antioxidant.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
- antioxidant
- vitamin
-
5
Hydroxypropyl Guar Hydroxypropyltrimonium Chloride
General function
A guar-bean conditioning polymer that deposits during rinsing. It is why a strong shampoo can still leave hair combable.
Estimated lower-concentration zoneIt 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 holdGums thicken and set soft, which gives definition that bends rather than a rigid cast.
May suitFrizz-prone, damaged, or high-friction hairCationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
May suitMaximum-hold stylingA styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
- conditioning agent
- polymer
- gum
-
6
PVP
General function
A classic hairspray polymer. It gives firm hold but attracts moisture, so humidity can soften the set.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
PubChemMay suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
DependsBuild-up-sensitive routinesSome acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
DependsCurls or waves needing flexible holdIt sets firm on its own. Whether the curl stays flexible depends on the plasticisers and oils the rest of the formula carries.

- polymer

Disodium Phosphate

A buffering salt that keeps pH stable as the product ages.

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
- 1.06 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 $42 is the price we have observed for the 1.06 oz. We need three stores before we call a price commonly seen.
- Good value under $3 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.29/oz; at 1.06 oz that is $3. Under that line you are paying less than most of them.
- About $5 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1.06 oz.

The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.
Does the same job, for less
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

Final decision
Should you buy it?
Good for the right person, not the lowest costBest user
People sensitive to fragrance who want a formula with no added fragrance and a product with no scent
Biggest tradeoff
Not ideal for soft, over-stretchy hair that needs protein, very dry hair that needs water-binding, or coarse, very dry hair that wants real richness
Best alternative if not

Claims check
What the brand says, and what the formula shows
Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

How this page was made
- Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one 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 (0 manufacturer or regulatory, 2 retailer, 2 editorial), last checked 2026-10-17.
- Ingredient references are linked for 4 of 7 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- 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 v23. Record last updated 2026-10-17.
