seanik*, lush's solid shampoo, makes the need to perfume one's hair obsolete; it smells of mimosa and jasmine - two of earth's utterly sexiest scents, and using it leaves just a hint of their seductive aroma on the locks. plus the puck is packed with sea salt -- which means tons of added volume at the roots. i live for a sea salt shampoo.
solid shampoo takes some getting used to, but just break off a tiny chunk of this product and work into your scalp and you'll be a convert. it comes in a small silver tin, making it extra convenient for travel. $10.95 at lushusa.com.
