Hi I'm a teenager and I now shower everyday because my hair gets greasy after 1 day out. People have told me that it is because I shower everyday? I don't know how it started as I didn't always shower everyday but now I need to shower everyday because I hate greasy hair as I think it looks very dirty and unhygienic. Anyone have any idea why this is?(I'm a very clean person BTW).And any suggestions on how i can stop this??
