I tried this mousse on my dry hair and wet hair, on two separate occasions. Definitely use after a shower or at least wet your hair before using, doesn't really work well with dry hair, at least not for me. I have shoulder-length, thick, straight hair. I tried using the mousse and scrunching, but my hair just ended up oddly wavy. It did stay like that for a while throughout the day, but straightened later. My hair doesn't like to curl or do much, though. Maybe I just need a new technique! I would still recommend this product. I tried it for free, but all opinions are my own.
