I wash my hair every third day. So if I wash it Monday, I'll wash it again Thursday.
If something gets in my hair or if I end up sweating to the point of it being very damp, I will wash it early.
I can only wash my hair every three days or so. If i wash it more than that, it's nothing but a static electricity filled mess because the air is so dry here.
It depends on the week and how my hair/head feels.
My hair is washed in the evening, and again in the morning. Then again anytime he wats to bathe me..
