, this formula targets the greasiest scalps.

amika formulated this specifically for oily scalps, and the specs back it up: it uses oil-absorbing tapioca starch and odor-removing bamboo stem extract to revitalize greasy strands. Clinically proven to remove more oil than the brand’s standard formula, it’s ideal for hair that turns oily within hours.

Buyers report it finally lets them skip a day between washes, with one reviewer mentioning they “always had to wash my hair every day due to oils, and this dry shampoo finally let’s me skip a day in-between!” The 3.53-ounce size is compact but the formula is dense enough that a few sprays go a long way.

If you have very oily roots and are willing to pay for a dialed-up formula, this is the most targeted pick on the list — but check the nozzle carefully on your first spray.

Delivers a 72-hour refresh with an invisible finish that leaves no white cast on dark hair.

Nexxus packs this 5-ounce can with their Flexx-Adapt Technology, which the brand says adapts to your unique oil levels for long-lasting freshness. It is designed to remove sweat, dirt, and odor molecules while leaving a soft, shiny finish that feels like an in-shower shampoo. At 5 ounces, it holds noticeably more product than the 3.2-ounce OUAI bottle — 5 ounces versus the OUAI’s 3.2 ounces — so you get more applications per can.

Customers note it is truly invisible on dark roots with no powdery residue, and the fine mist refreshes hair instantly. The main complaint is the spray mechanism: one reviewer noted “after a couple uses, it just seems to not spray anymore,” and several others say the button is hard to press or the stream comes out too strong. When it works, the formula is top-tier for oily hair — the catch is whether the bottle will cooperate.

Plant-based nettle extract absorbs oil in 25 seconds and tints to blend into dark hair.

Klorane takes a different route from the starch-heavy formulas. It uses nettle, a plant that naturally helps regulate oil production, to cleanse greasy roots. The brand says it removes excess oil and impurities in just 25 seconds, and the naturally tinted minerals blend into dark hair without leaving a grey or white cast — a common frustration with standard dry shampoos.

Shoppers say it controls extreme oiliness for 2 to 3 days, making hair look freshly washed, and one reviewer who tried over 30 brands called it “THE BEST DRY SHAMPOO EVER.” The 3.21-ounce can is smaller than the Nexxus or Divi options, but the formula is concentrated enough that a few sprays handle a full head of greasy roots. The trade-off: some users find they need to use a fair amount to get the full effect, which makes the can go fast for daily use.

A travel-friendly format that blends smoothly with zero residue, even on greasy hair.

OUAI redesigned their Super Dry Shampoo to absorb oil, dirt, and sweat while blending smoothly into hair — the brand emphasizes it leaves zero residue even on dark strands. At 3.2 ounces, it is the smallest can on this list, making it TSA-friendly for frequent flyers. The Melrose Place fragrance (bergamot, lychee, white musk, champagne) is a major draw, though the scent is intense enough that sensitive noses should be warned.

Buyers report it “works well for extending time between washes, even for greasy hair,” and many say it is the best dry shampoo they have used despite the higher per-ounce cost. The aerosol blast is powerful — the instructions say to spray 6 to 8 inches from roots — and it dries fast. The catch: the fragrance is described as “incredibly strong” and lingers for hours, so if you are sensitive to heavy scents, this might not be your pick.

A benzene- and talc-free formula that works with your scalp, not against it.

Divi stands out by ditching common propellants: it is free of benzene, butane, propane, and talc. The Balance Blending formula uses micro-algae to protect hair from breakage and pollution, plus a rice and cornstarch blend to absorb oil. At 5.3 ounces, it is the largest can on this list, so you get more product per purchase compared to the 3.2-ounce OUAI or 3.21-ounce Klorane.

Owners mention it controls oil very well and boosts volume, though it can leave a white cast if not applied properly — the cast brushes out, but it is an extra step. The scent is sweet and strong, lasting all day, and many appreciate the cleaner ingredient profile. A few customers note it does not perform noticeably better than less expensive options, so the value depends on how much you prioritize a benzene-free formulation.

A fragrance-free, aerosol-free powder that relies on rice starch and tapioca to soak up oil.

This is the only non-aerosol option in the lineup — a pump bottle dispenses a lightweight powder made from natural rice starch and tapioca. It is unscented, talc-free, and safe for color-treated hair, which makes it a solid choice for sensitive scalps or anyone who dislikes fragrance. The 2-pack gives you two 5.29-ounce bottles, so the total capacity is generous — each bottle is 5.29 oz versus the OUAI’s 3.2 oz — but the pump delivery is where things get tricky.

Reviewers point out the pump fails with more than 50% of the powder still left in the bottle, poofing powder everywhere and leaving a white residue that does not brush out easily. The powder itself works well when the pump cooperates, giving roots a fresh lift and absorbing oil effectively. The 2-pack is a great value proposition, but only if you accept the risk that the pump may die on you before the powder runs out.
