Dry shampoo has one real job, and most of the sprays we tested do it for a few hours before the roots flatten again. IGK First Class kept going. It's a charcoal formula aimed at oily scalps, and it was the most reliable of the bunch at cutting grease on third- and fourth-day hair while keeping the volume it added.
The finish is what we didn't expect to like as much as we did. It's built to be invisible, and on most hair it is: spray at the roots, give it a minute, work it through, and it disappears. Two or three short bursts also give fine, flat hair some grip and a little beachy texture, which is handy when you're stretching a blowout. Overdo it and that grip turns stiff, so start with less than feels sufficient.
IGK is also unusually specific about what isn't in the can: talc-free, sulfate-free, paraben-free, gluten-free, vegan, and Leaping Bunny certified. If clean is the reason you're shopping, that list does more work than a botanical illustration on the front.
It's one of the pricier single cans here, and concentration is the argument for it — a couple of short bursts at the part do the job, so you're not soaking your roots every morning. It's also listed as safe for keratin- and color-treated hair, which matters if you've paid for a smoothing treatment.
Pros
- Absorbs heavy oil and keeps roots clean for days
- Lightweight finish that disappears into the hair
- Adds volume and grip to fine, flat hair
- Talc-free, vegan, and Leaping Bunny certified
Cons
- Can leave a white cast on very dark hair
We recommend this one for genuinely oily roots: it absorbs the most convincingly of the sprays we tested, brushes out clear, and keeps hair looking fresh for days.
