Needing help

I’ve had dry skin for a long as I can remember. My hands, face and ESPECIALLY my scalp are the worst. I got lice back in March and even though they’ve been long gone it’s only made my scalp much worse. I’ve never really been given a lot of advice growing up my parents touch me to believe that conditioner is just a waste of money. So I don’t really know what to do except shave my head off but I’m tired of having to shave my head over and over again I want to have long nice hair that can look cute with cute outfits.

Please if anyone knows what I should do I would greatly appreciate it xx
