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.
Fast-drying alcohol in the first three ingredients.
Nothing here needs a detergent wash to remove.
Fragrance is listed; it sits below the working ingredients.

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

Distearyldimonium Chloride
General function
A rich conditioning agent used in heavier masks for detangling and a coated, smooth feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitFrizz-prone, damaged, or high-friction hairA cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
May suitVery dry or highly damaged hairThe class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.
DependsBuild-up-sensitive routinesSubstantive by design. A routine with no detergent wash gives it nothing to leave with.

Zea Mays (Corn) Starch
General function
A starch that soaks up oil at the roots and adds texture.
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.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

Pisum Sativum (Pea) Peptide
General function
A short-chain pea protein used for strength and body claims in vegan formulas.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
DependsVery dry or highly damaged hairUnhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.

Ethyltrimonium Chloride Methacrylate/Hydrolyzed Wheat Protein Copolymer
General function
A positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.

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.

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.

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
- 3.5 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.
- Commonly seen is the middle half of current prices for the 3.5 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $17 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $4.80/oz; at 3.5 oz that is $17. 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 $19 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 3.5 oz.
Dry shampoo refreshes hair between washes. We describe its ingredient functions without assigning a formula score.
Does the same job

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 it did little to absorb oil and sometimes left hair greasier.
Reviewers with fine, thin or oily hair, including several who used it for a next-day refresh or as a night-before application.Several reviewers report a white or powdery residue that would not blend in.
Reviewers across several hair colours who saw white powder at the roots or on the scalp after spraying.Reviewers call the price high for a can that empties quickly.
Reviewers who bought at sale or full price and who felt the can ran out after a few uses.The strong, lingering fragrance is the most frequent complaint reviewers raise.
Reviewers of thin, fine and thinning hair across both sort orders; a few reviewers praised the same scent as light and pleasant.Volume results are split, with some reviewers seeing lift at the roots and others seeing none.
Reviewers with thin, fine or thinning hair; several said it lifted or thickened the roots, while others said it added no volume or flattened the hair.More from Drybar
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.
- 4 sources consulted for this product (0 manufacturer or regulatory, 2 retailer, 2 editorial), last checked 2026-10-31.
- Ingredient references are linked for 12 of 17 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.
