Am I shedding? Cooked? Progress seems to be regressing

Description

I started 1 mg Fin daily in Sept 2024, started derma stamping twice a week at 1.25 mm twice a week around two months later, and started to see noticeable progress within a few months. Well, I took my monthly progress photo a few days ago and noticed how much of my scalp is showing through again. Am I in a shed phase? Is this as good as it’ll get? Should I start adding oral or topical minoxidil to my routine. Thanks for any guidance and honest, informed takes!
