I like the spray for what it does to my hair as it definitely enhances my waves.But...The smell is overwhelming. To me it smells like old perfume and it does not diffuse. Even after several hours it still smells very strongly to the point it induces headaches. I doubt I'll be able to get through the whole bottle

Now become a staple when styling, I wash my hair, then when wet use olaplex oil then cream then the wave spray and it makes my Bob soooo good 

This helped my hair hold its shape, and give it volume.. that being said I can't put this near me again. I like how it looks in my hair but the scent (which is an unnecessary ingredient) made my scalp itchier than every preschool lice outbreak I've experienced. Usually I don't mind fragrance in hair products, if it at least went away in some time.. not the case here. The smell clings to your hair like ants to popsicles, same problem with the volume spray. Sitting in a freshly painted room is less nauseating. Reading reviews of people going on about how good ouai products smell makes me wanna go pray and cry. And I'm not even religious

My hair has a natural wave but is thick and heavy so I really wanted this to work, but it just didn't. It created waves on my damp hair but every time I tried it they were gone once my hair dried. I gave mine away to someone with short thin hair.

I do love the smell and how it makes my curls but it tends to get heavy on the hair.
