For all of you who thought that the function of baby powder was to keep your feet, underarms, backs of your knees cool and dry, I've got one more for you. You can use baby powder on the roots of your hair!
Say you are feeling a little greasy in between washings, or you overdid it on the styling products. Just put a little powder on your comb and brush from roots to ends. This will help absorb any unwanted greasiness.
It is the same concept as using a dry shampoo, only baby powder isn't going to cleanse your hair or make it smell as good as a hair fragrance would. However, it will get you through the day feeling slightly more refreshed, and your hair will definitely be softer and more manageable.
