How to shower with DE hands?

I have DE on hands and they’re super itchy, there’s some raw and broken skin from all the scratching.

I don’t really know how people shower or bathe or wash their hair when the DE is on the hands? I’ve tried rubber gloves but I have gotten water in it. Tying it with a rubber band or taping it irritates my skin due to the friction or heat.

I also tried wrapping with a plastic bag but it’s so hard to shower or bathe like that.

I’ve tried those plastic clear bandaids to protect a wound from getting wet but those are not cheap and it seems so wasteful to be using one a day or even a few a week. I’ve kept them on sometimes but it smells so bad after just a couple days.

Any other suggestions are super helpful!
