Dry shampoo, but should be improved. I bought one long ago out of curiosity but never used it until yesterday. As it happened, I didn't bath for a week or so. I didn't smell (despite some physical work, helping the movers - I'm not like Keira Nightley), but my hair annoyed me. I reached for the dry shampoo (which was the only thing left in the bathroom) and generously sprinkled it on my head. The powder soaked in all the dirt and oil, leaving my hair a bit stiff, but feeling much fresher. I could go on like that for another week, I think, but as I got access to a fully stocked bathroom, out of curiosity I took a bath (to remember what it's like). I quickly regretted it. The dry shampoo in my hair turned into clay and it took me thrice as long to wash it off. The current dry shampoo formula is a one way street.
