1. Start by adding texture and volume with a sea salt styling spray—our top picks are featured in this curated selection. For thick hair, section it into two parts: clip up the top and spray only the bottom layer first.
2. Give it a quick pass with the blow dryer, then brush through smoothly. Divide the hair into four sections and loosely braid each one.
3. Mist each braid generously with hairspray, then use your straightener with gentle pressure, working from root to tip along the braids.
4. Remove the elastics and finger-comb to loosen the waves. Finish with a light spritz of hairspray for lasting hold.
And voilà! You've mastered mermaid waves—beachy, effortless, and salon-worthy.
