I use this leave-in spray on damp or dry hair. On dry hair I find it works like a hair serum to help control frizz while producing shine. On damp it definitely provides shine, however does not replace my need for a leave in conditioner to control dryness. It applies an even mist like spray without clogging. Only a small amount is needed for the desired effect so the bottle does last. Unfortunately, I find it has a very strong and odd yet familiar (and not horribly unpleasant) scent. I do think this is just a preference of mine, others may like the smell.
