How to get rid of acne and blackheads on the nose?

I just hit puberty so my skin if super oily. I get acne(pimples and zits)all over my face. And one is even on my neck! my parents can’t afford a dermatologist. I’m not allowed to use any blackhead removers for my nose because my mom said that will only damage my skin. My mom does let me buy a face wash from Neutroguiena, it’s the one Vanessa Hudgens did the add for. The face wash calmed down my acne for a little while but than it started up again. My aunt told me that my hair(I have dandruff, hey how do you get rid if dandruff??)causes my acne so I’m wondering if it’s true. So any natural ways to remove acne and blackheads? thanks a bunch! and if you know how to get rid of dandruff please tell me! oh yeah and don’t tell me to use pore strips or to try to squeeze out the blackheads, it doesn’t work for me
