Some of the dry shampoos leave a white residue and shows up on dark hair....I don't have that problems since my hair is light. I read reviews on Ojon and I don't believe anyone with dark hair had any problem with the white residue but can't attest to it personally.Bumble + bumble had one that I tried but the "blondish" color was quite dark. Maybe the "white" one would've been better. Baby powder would work as well I guess if your hair is light.
I will try Ojon! It might work, thanks!
