I have thin, blonde, typically Nordic hair and this worked quite well on my hair. I usually get greasy hair the same day I wash it, and this allows me to go 2-3 days without washing it.
The hair gets a bit dry and straw-like, and if I run my fingers through my hair, I can feel that there is product in it. I also struggle a bit with the application as I get white spots on my body from the spray. It gets wet first before it dries, unfortunately, it also dries out my scalp, and I get a dry and "flaky" scalp. This could of course be a user error on my part. I also experience that my hair gets a bit static?
