If dry shampoos from Batiste and Bumble and bumble aren't up your street, but you'd still like to check out a hair powder, then consider offerings from Schwarzkopf and Aveda. Dust It (left), €12.75, is from Schwarzkopf's Osis styling line, and on the right is Aveda's Pure Abundance Potion, €17.
Both are teeny little bottles of white dust that can be used to thicken and add texture to hair, and while they're styling products and not dry shampoos, they will work to give you a bit more life out of a blowdry.
How to use? Shake into your hand and apply straight to roots to give texture and a bit of lift and volume. Plus the Aveda product transforms mysteriously into a paste in your palm, meaning it's super-easy to get into partings and work with.
Buy both from HQhair.
