I recently received this product as a sample, and to be honest, I had no idea what to do with a sea salt spray. I have naturally very dry, very curly hair and thought, there is no way salt could be good for it. One day I ran out of my usual product and decided to give this a shot, I was very pleasantly surprised. My curls seemed much fuller and my hair had a ton more body. Another bonus, the spray has the slightest bit of hold so I didn't have to work about my curls breaking up throughout the day.
I think this spray is amazing, if you have any doubts about it, don't.
