Do you wash behind your ears?

[Mydriveways]

It’s just occurred to me that I’ve never done this. Is this gross?! I guess shampoo runs down when I wash hair. I’m feeling sick with morning sickness and have had a lot of time to think while in bed recently!

And what?

Yes, sometimes when I wash my face or hair.

I wouldn't worry about it though. I think the whole concept comes from when people strip washed in a sink. Now we mostly shower daily and tend to wash our hair a lot more often, we're much less likely to get grime building up.
