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.

Works for me. Every evening at 10 I need to take my meds. I feed my cats their dinner right after. At 9.50 they all come to where I am and start demanding food. I never forget my meds.
