I used to use it when going to my family in laws. Their shower is god awe-full, spending half a hour in semi tepid water not even strong enough to rinse all the soap out of your hair. At least with dry shampoo i could skip a day of that.

Thats how I got married. Asked some guy I knew on msn messenger to help me with my computer problem. He got really upset and ranted about people only reaching out to him cause they needed their computer fixed and never to ask how he was doing. So I asked him how he was doing. Married for nearly 20 years now.
