I heard about this a long time ago. If you have greasy hair and you don't have time to shower, you just rub a bit of cornstarch in your hair and it isn't greasy anymore. I don't have the opportunity to shower a lot but I don't want to leave the house with greasy hair so I tried this and it worked great. I didn't take pictures because I didn't think to but next time I will try to remember. Didn't even need a lot of cornstarch.
