Don't have time to get wet? Here are four more reasons to try Tresemmé Fresh Start Waterless Foam Shampoo ($5; drugstores):
1. It's easy to apply. (Gently rub two or three pumps onto hair, pat dry with a towel, and go.)
2. It's a clear foam, so it doesn't need to be brushed out (a bonus if you want to preserve your curls).
3. It contains witch hazel to absorb oil from roots, and aloe vera to keep hair hydrated and shiny.
4. It leaves no residue, so your hair looks squeaky clean and refreshed.
