For some people, their hair starts to look or/and feel greasy if they skip showering for one day. When I don't wash my hair for three days, it feels oily to the touch. If I were to run my hand through my scalp, my skin end up with a slight shine to it. So you have to imagine how embarrassing it is for someone to realize that you haven't wash your hair by just touching it. ( ̄∇ ̄")

How is he going to notice you didn’t wash your hair just by touching it? I don’t have hair like that so I wouldn’t know.
