Let me get this straight.AtheistGuy said:So to make a long story short, I have dandruff. This dandruff bothers my grandfather (Who I live with). I don't want to use any shampoo for it since it, quite honestly, doesn't bother me in the least. So he's taken it upon himself to actually put some drops on my head to get rid of it. The problem? I'm asleep when he does it.
SO it's a pretty straightforward question. Is this acceptable?
You have a severe(or at least notable) dandruff problem to the point that your father's father is bothered by all the deceased epidermis you're littering around the place and when he asks you to wash your hair when you take a bath/shower, you are saying no? Thus forcing him to take drastic measures?
What is it about washing your hair semi-regularly that bothers you? Are you afraid that it's poisonous or damaging to your scalp? Are you against hygienics in general?
