Beach Hair

Totally achievable sans beach.  My two favorite products, both add body and great texture to hair:

From Australia, Kusco-Murphy Beach Hair has the most fantastic coconut smell with pieces of crushed bamboo to replicate sand.  Available on amazon.com.

Bumble and Bumble's Surf Spray has the same effect but is a bit lighter.  It uses salt, then seaweed and kelp to add moisture. Available at sephora.com.
