In the Philippines, dry shampoo isn't often used since it's so hot and humid, people just wanna shower all the time. Sometimes, even twice in one day.
But there are times and reasons for not washing your hair everyday. As for me, I generally wash my hair daily, but there are time when I don't: Not enough to justify my buying a dry shampoo but enough for me to want one.
So what do I do?
I use regular baby powder.
It works :)
