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. These 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
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)

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/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 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
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 this point, order stops being meaningful — these are typically 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.

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

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.
Seen at $18.89 is the price we have observed for the 0.7 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 $4.68/oz; at 0.7 oz that is $3. Under that line you are paying less than most of them.
Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
About $20 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 0.7 oz.

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.

Final decision

Should you buy it?

Good for the right person, not the lowest cost

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, 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.

SupportedBacked by ingredients

Partly supportedSome supporting logic

Stated by brandNo clear evidence

Potential conflictFormula works against claim

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 marketing. If the list doesn't speak to a claim, we don't assume.

Reviewers

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not 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 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.
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 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.
