Sea salt adds texture and body to straight hair. It can also be suitable for styling, as it provides extra grip, which can be needed for straight hair, especially when it’s clean. While it won’t necessarily immediately give you beachy waves, it can help create the look with a little bit of work. Scrunch sea salt spray through your hair from root to tip, and either twist or braid into two buns. Let it dry completely before taking it out and enjoying your tousled look.
