Summer and surfer girl waves go together.  Here's how to get that sexy tousled texture:

On fine hair-Use a thickening spray, and before bed, braid 2 inches from your scalp, and in the a.m. unbraid and spray a dry texturizing spray on for more fullness. 

On short hair-take a 1/2 section forming a loop, secure with Bobby pins, dry and remove pins.  Use a molding paste to play up the piecey-ness.

On thick hair-On damp hair make 4 sections and split in half, and tie in a knot as if you were tying shoelaces.  The crisscrossing brings out the waves in a more natural way.

     Or........you could just head to the beach🌞🌞🌞
