I wonder two things about girls washing their hair:

I wonder how often girls wash their hair on average?

I wonder why some girls get so upset when their hair gets wet after having washed it?

The reason I ask is because a girl I was get her hair a little wet freaked out and said "In just washed my hair!" It seemed to me, "who cares if u just washed your hair? It will dry."

I wonder what I am missing there?
