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.

Hold system Wax

Gums and synthetic polymers together.

Cast risk Unlikely

Softening ingredients sit alongside the film formers, so a hard shell is unlikely.

Weight on the hair Light

Water-first and light: unlikely to flatten fine hair.

Oil absorption High

Absorbent powders or starches high in the list.

Oils and butters None

No oils or butters in the list.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Fragrance None listed

No fragrance is listed.

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.

IngredientWhat it doesWhy it mattersChip
WaterAqua/Water/Eau solvent The base everything else is dissolved in Neutral
Propylene Glycol humectant Pulls water into the hair Moisturizes
Silica Silylate powder Mattifies and absorbs oil Stabilizes
Citric Acid pH adjuster Fine-tunes the pH pH balancer
Sodium Benzoate preservative Keeps the product from spoiling Stabilizes
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 (5)

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 Water · Aqua/Water/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 Propylene Glycol
    General function

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

    Leading ingredient

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

    May suitFine or easily flattened hair

    Light and water-binding rather than oily, so it adds less weight than oils or butters do.

    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
  • 3 Silica Silylate
    General function

    A treated silica used to absorb oil and add grip in texture products.

    Leading ingredient

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

    May suitFine or easily flattened hair

    A dry powder takes up oil and adds friction between strands, which is most of what root lift in fine hair actually is.

    • powder
    • thickener
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 4 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.

    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

    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
  • 5 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.

0.7 ozusual store sizeBest per ounce

0.3 oz

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. 0.7 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.
  2. Seen at $21 is the price we have observed for the 0.7 oz. We need three stores before we call a price commonly seen.
  3. Good value under $25 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $35.14/oz; at 0.7 oz that is $25. Under that line you are paying less than most of them.
  4. Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
  5. About $36 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 0.7 oz.

Formula

Formula score
7 of 10

It costs more per ounce than 89% of the 143 volumizers we’ve priced. The formula covers the core of the format, and we do not have a close match at a lower price.

How the score is counted
  • 1 products we score as doing the same job cost less per ounce
  • Costs more per ounce than 89% of the 143 volumizers we’ve priced
  • No softeners alongside the hold in the formula

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?

An above-range pick for the hair it suits
Best user

People sensitive to fragrance who want a formula with no added fragrance and a product with no scent

Biggest tradeoff

Worth skipping for very dry or very humid climates, frizz on humid days, or anyone who wants a product to smell of something

Best alternative if not

OCOA Curl Refresh + Hold Spray, for similar results at a lower price

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, 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.

Delivers anti-gravity volume, lift and thickness with a matte finish

It reads light on the strand, which is what volume claims depend on.

Supported

Leaves room for lift.

Can be layered with other styling products for enhanced texture control

This is a marketing claim; an ingredient list cannot speak to it.

—

Stated by brand

Can’t be confirmed from label.

How to read this

We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.

Reviewers

What people report

Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.

Reviewers with thinning or fine hair say the powder provides lasting texture and volume all day.

Several reviewers value that the product is effective on hot, humid days without adding oiliness.

Multiple reviewers say a jar lasts a long time because only a small amount is needed per use.

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.
  • 5 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 4 editorial), last checked 2026-09-12.
  • Ingredient references are linked for 2 of 3 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 2026-09-12.
