Dirty Hair

Caps are quite common in other countries, as sometimes are tight fitting swimwear to reduce the amount of hair that might come from, well, not your head.

My missus is a hairdresser and barber, she says mostly young fellas that are the worst for dirty hair

what about Muslims with big beards do they need beard hats ?

I'm not Muslim (I wouldn't be able to give up pork products), but I do have a big beard. In the few occasions I've gone swimming since having a big beard, no one has ever said anything. But in my defence, I tie it up if I'm going swimming. Mostly because if I didn't I'd look like a wet homeless person. And I can't do the slow mo wet hair flip women do, except backwards. I'll take my eyes out.

But in my extremely limited employment in a barbers (I was 17, I was sweeping floors and got "promoted" to washer), the dirtiest hair were the men who think coming straight from a building site was acceptable. Trying to wash steel out of already wiry hair is not fun.
