4. Hair Appearance
Not only will your hair style better, your hair will also look better. Everything seems to stay in place better on Day 2. You won’t be as bothered with frizz or dry looking tresses after skipping the shampoo. If your hair does looks a little greasy at the roots, simply spray on some dry shampoo or baby powder. I know it may sound crazy, but you'll be amazed how much better your hair looks the day after you skip a wash.
