I guess that depends a lot on your level of activity. When I was your age my normal routine was a shower and washing hair everyday. That continues to be my routine now.
Is this a normal routine? Sunday - have a complete bath; Tuesday - wash hair only; Thursday - wash hair only. The other days I don't do either. I'm a 14 year old girl.
Maybe that's normal for someone like you. It really depends on the person how they do their routine. Some I knew back then does shower 3 times a day, so we can never tell what's normal or not for some people. It may work for you but for some might not.
I pratically don´t sweat and I don't do exercise so thanks for the answers
