Odd question but how often should I be showering?

Jordyn
I've heard plenty of different things. But when I was in school I would shower Every night or 2. And then as I got older I change it to 2 to 3 times a week. My hair is way worse then before. And I feel more tierd. Should I start showering more ? I want my hair to grow but not if it's causing me to feel so depressed.just really curious !
