usually once a day. There are times I wash my hair 5-6 times a week. I don't feel comfortable not washing my hair >.< I'm afraid that it might smell icky. haha.
Every day - once a day. I just think it already looks dirty the next day... maybe it's just my imagination, but still, I have to wash it every morning.
i wash my hair everyday with shampoo and conditioner... if i sweat a lot i wash twice... it really depends on the climate...here in the philippines we take a bath everyday or else you will have foul smell...that's awful!!!
