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.
Yes, I am sure. If I don't use at least mild shampoo and shower gel, my hair gets greasy and my skin oily, minutes after the shower. That causes even more problems.
Ok at least you are sure, that's all I can ask. :)
