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.
Oil-absorbing ingredients
High in the list
Absorbent powders or starches high in the list.
Fast-drying alcohol

No
Nothing here needs a detergent wash to remove.
Fragrance
Prominent
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Full ingredient list (23)
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.

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.

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.

A starch fragment that soaks up oil and water, which is what puts it in dry shampoos. It also carries spray-dried plant extracts and leaves a light 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
- 6.3 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 6.3 oz. We need three stores before we call a price commonly seen.
- Good value under $6 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.96/oz; at 6.3 oz that is $6. 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 $9 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 6.3 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.

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.

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.
Many reviewers say the spray leaves oily roots looking greasier, flatter or heavier rather than absorbing oil.
Mostly lowest-rated reviewers, many with oily, fine or thick hair, who said it did not absorb oil after use.Reviewers compare the price unfavourably with cheaper dry shampoos they say perform better.
Lowest-rated reviewers who had bought other dry shampoos, including drugstore and salon brands, for comparison.A recurring complaint is that the spray nozzle clogs or stops working before the can is empty.
Reviewers who had used the can for a few uses or weeks and found it still half or more full.Several reviewers like the light feel and the lack of white residue, though they do not credit it with oil control.
Reviewers who judged the product on feel, residue and fragrance rather than on oil absorption.More from Olaplex
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.
- 3 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-31.
- Ingredient references are linked for 9 of 16 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.
