» WHAT IT IS: A round bar of cinnamon and clove shampoo from Lush that can be kept in a travel tin.

» THE GOOD: It’s hard not to overstate the case: This stuff is great. You may never use a liquid shampoo again. Wipe the moistened bar on wet hair. Because it’s a solid, the shampoo is a natural for carrying in lieu of a liquid that bothers the Transportation Security Administration. Other kinds of Lush solid shampoos are also great to rotate into your routine, along with the solid conditioner. The bars also will make your hair (and bathroom) smell fantastic.

» THE BAD: You cannot place the wet shampoo bar in its tin or let it lie flat without having it adhere to a surface. If traveling, mop the excess moisture off with a towel, then let it dry for a half-hour standing on its edge.

» COST: $10.95 for 1.9 ounces (tins cost $3.95)

» AVAILABLE FROM: lushusa.com, Lush stores and select Macy’s
