Reversing an M shaped hairline loss

I am using minoxidil, zinc, and biotin plus Dermaroll once a week. I believe that Minoxidil definitely works even without fin!

It would be unlikely to reverse this frontal M shaped hairline, but I would try with microneedling + minoxidil and use topical finasteride. After one year you will know. IF it doesn’t work a hair transplant is a good option.
