Lasting scent + best hydration. Best hydration of Old Spice Body Washes. Old Spice Hydro Wash is like a genie in a bottle that with continued use will make all your wishes come true, so long as those wishes are limited to: Fighting dry skin at the source. Removing clods of dirt from your body. And smelling great. In that sense it's probably the worst genie in a bottle in history, but an excellent body wash nonetheless.
