Scalp no longer produces ...sebum?

No, i'm not on any medications, but recently i used two bottles of antibiotics (for flu and a cut on my hand) maybe that's a side effect?

Antibiotics for flu don't make sense. Antibiotics kill bacteria, including good ones in the gut. A flu is a viral infection.

my mom's very sensitive about a healthy diet;

Could you explain this?

I agree about sufficient fat. Not just omega-3, but also olive, coconut, and others. My main source of fat is avocados, but I include others in small amounts.
