This is the only dry shampoo I've ever used, so I wasn't sure what to expect. I have oily hair, needing to wash it every other day if I don't want to look like a dirtball. This allows me to skip that wash if I don't have the time to do so, removing all traces of oil from my hair & restoring volume. It smells like vanilla & spices, it's a pleasant smell, but it can be overpowering. I don't use it often enough to notice if it does rejuvenate your hair in the long run, but it does an amazing job with each use.
