Unscented dry shampoo

[Mcmcmcmc]

Is there such a thing?
Or at least one with a very mild scent that does not walk into a room before you?

Can't swear by these as never used, but Amazon UK has A'kin Mild and Gentle dry shampoo and Batiste Dry Shampoo in Bare, both of which claim...

Lush powder in a bottle.

Alternatively cornflour.
