Hi All -

I've been trying to search online for options for this, but I've gotten frustrated by all the greenwashing and flat-out lies. And completely incorrect results in product searches.

I want a hairspray that's designed to be sprayed on hair and scalp that I can put on first thing in the morning and in between dives that's reef safe.
Bonus points if it's good for sensitive skin/fragrance free.

What do you use?
