Just out of curiosity, is it bad to wash your hair without shampoo? I was told that if you wash your hair without shampoo, the water will actually make your hair smell worse. Wasn't sure how true it was. I take a shower every day, but every so often, I may run out and may go part of the day without it, which means I take a shower without it. Wasn't sure if it was wise to still get your hair wet or not. Also wondered if it depends if you have long hair or not.

Also, what is the longest an average person can go without washing their hair before it smells? I always thought it was no more than a day or so as long as you don't do too much physical activity or be anywhere that may make you sweat a lot. I know for everything else, it is best to wash every day, just wasn't sure about the hair part. I wash mine every day, I am just curious if what I was told is true or not.
