Curiosity only.
Here in Brazil it’s very common to have several showers a day. I, for example, take two. The first is when I wake up, before I go to work, and the second is when I get home from work. I wake up at 6.30am and get home at 8pm.
edit: I said bath, but I meant shower.
Florida here.
Once a day in the evening, unless I really get sweaty in the day (yardwork or hot yoga) then twice but soap (not everywhere) once a day, shampoo about twice a week, but rinse, conditioner, and restyle hair most days.
Husband washes like OP, in the morning before work and in the evening too. It’s hot here.
