I had a friend try the 'no shampoo and deodorant' thing that's been so seemingly popular recently. She swore up and down that after a week she had 'normalized' and had never felt fresher. Of course, her hair was a good bit greasier than usual, and her smell had changed, not bad, but different.

I'm pretty sure the 'normalization period' is all about getting used to how your body feels without soap, shampoo or deodorant.
