I wash my hair every other day... no exceptions (unless I have hairspray in it, because then I would want to wash it as soon as humanly possible).
My scalp gets itchy, stinky, and oily, dandruff-y after the first day. It bugs me so I run my fingers through my hair too. It has gotten to the point when sometimes I would question whether other people can smell it.
It's funny because when I was young, my scalp was never like that. My mom washes her hair once a week and she puts on hairspray every day, styles it, etc. It's disgusting thinking of how much built up there could be... and the stench too!
She always complains and tells me to wash it every once a week because she likes the natural oils and she thinks that washing every other day will make me lose my hair. But I can't stand not washing it!
