Is it time to cut my hair off?

I feel my hair has gone way too thin on the top. And I can't control anymore. I'm thinking about going for minoxidil. But I ain't sure how much it'll work. Way too much dandruff and receding sides was already tough to manage , but it was still looking good. Now once I discovered this , I am thinking about not keeping my hair at all.

[ The pics here don't show my normal hairstyle. I disheveled it and parted it around the balding areas. Plus I have vitamin B12 and Folate deficiency. And I don't like fruits 😭.]
