I saw this on the Free People Blog and thought it I would pass it on.
the relaxed wavy look
first, slightly dampen hair with a styling spray – she uses bumble and bumble (but im sure any flex hold hairspray, spray gel, sea salt spray will do the trick).
next, separate the hair into two pieces down the center. then separate those two into two. start with 2 strands, either the left side or the right of head, and twist the hair away from the face. then take the 2 twisted strands and twist them together. secure on top of head with a hair clip.
once the product has had time to dry, remove the clips and shake your hair out girl.
