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.
Absorbent powders or starches high in the list.
Contains fast-drying alcohol, which speeds drying but can leave hair feeling dry.
Nothing here needs a detergent wash to remove.
Fragrance is listed; it sits below the working ingredients.

Hydrofluorocarbon 152a
General function
A non-flammable aerosol propellant used in dry shampoos and finishing sprays.
Leading ingredientPubChemListed in the first three ingredients, it is likely a structural part of this formula.

Alcohol Denat.
· Alcohol Denat
General function
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairEvaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
May not suitDry, coarse, or high-porosity hairPorous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
May not suitVery dry or highly damaged hairIt evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.
- drying alcohol
- solvent

Aluminum Starch Octenylsuccinate
General function
A modified starch that absorbs oil and leaves a dry, matte feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFine or easily flattened hairAdds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.
DependsMaximum-hold stylingStarch gives texture and grip rather than a set film; firm hold usually needs a polymer alongside it.
- starch
- powder

Isobutane
General function
A pressurised gas that pushes an aerosol out of the can and evaporates on contact.
Supporting ingredientPubChemListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- propellant
-
7
Panthenol
General function
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.
May suitFrizz-prone, damaged, or high-friction hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
May suitVery dry or highly damaged hairA humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.
- humectant
- conditioning agent
- vitamin

Disteardimonium Hectorite
General function
A clay modified to thicken oil rather than water, used to give balms and pomades structure.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- clay
- thickener

Magnesium Carbonate
General function
A light mineral powder used to soak up oil and keep a powder free-flowing.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitFine or easily flattened hairA dry powder takes up oil and adds friction between strands, which is most of what root lift in fine hair actually is.

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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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.
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.
- film former
- polymer

Zeolite
General function
A porous mineral used to absorb oil and, in some products, to trap odour.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

14
Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-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 hairBinds 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 hairWater 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.

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 zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.

- hard-water chelator

Fragrance
· Parfum / Fragrance
General function
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.
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.

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
- 4.5 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 $30 is the price we have observed for the 4.5 oz. We need three stores before we call a price commonly seen.
- Good value under $5 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.05/oz; at 4.5 oz that is $5. Under that line you are paying less than most of them.
- About $10 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 4.5 oz.
Dry shampoo refreshes hair between washes. We describe its ingredient functions without assigning a formula score.
Does the same job
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.

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.
Most reviewers say it soaks up scalp oil fast and adds volume at the roots on second- and third-day hair.
Users with oily scalps and between-wash routines. Most of the 34 entries say the brand gifted the bottle, so weigh this one with that in mind.Many reviewers describe the Cape Town scent as fresh, light and clean rather than heavy, and say it is not overpowering.
Scent-led praise across the full star range, with several calling the scent subtle or airy.Reviewers often say the refresh lasts through the day, and several use it to stretch wash days by a day or more.
Users who want to extend time between washes, including people with busy schedules, workouts or travel.A few reviewers find the Cape Town scent strong or perfume-like, and one had to wash it out the same day.
Mostly 2- to 4-star entries that name the scent as a drawback, plus one 5-star reviewer who called it a stronger dry shampoo. The lowest-rated scent complaint is a 2-star entry.Dark-haired reviewers split on residue: most say no white cast shows, while two say a cast stays and makes hair look grey.
Reviewers with dark brown, dark blonde or brunette hair. The two who saw a cast were rated 1 and 3 stars, and one 5-star reviewer said no cast shows as long as it is rubbed in well.More from Ouai
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.
- This library-only category has no formula-completeness score or personal routine recommendation.
- 2 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 1 editorial), last checked 2026-10-31.
- Ingredient references are linked for 7 of 12 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 2026-10-31.
