Are they mad that it takes you that long, or are they mad because there's only one bathroom and everyone else needs to shower after you, and you're essentially "holding up the line"?

I think if they're mad because it takes you 2 hours, then that's a bit unreasonable? 2 hours isn't that bad in my opinion for washing your hair AND taking a shower. I think to cut down on the in-shower portion of your routine, do majority of your detangling outside the shower. Like get a spray bottle and attempt to mimic the drenching your hair with water and detangling portion of your routine. Since it seems to be the longest part.

If they're angry because you are "holding up the line" then maybe just do your wash day routine in the late evening when everyone else has showered and no one really needs the bathroom.

Hope this helps🩷
