Losing ground on finasteride after only 2 years of really good results?

Hopped on medication back in may of 2023 and had really great results since. I was diffuse thinning around the crown and frontal area, and in about 6 months my hair had returned to its initial full density.

However just recently, from March to April my hair density had dropped significantly (This photo was taken yesterday). I would also note that I did lose quite some weight (75-55 kg) from November to March so there might be some nutrient deficiencies involved especially because I was a bit iron and vitamin deficient prior and didn’t eat very well so it might just be a bodily stress response??

However there seems to be more miniaturisation than shedding going on

Im planning on incorporating microneedling but should I try switching to dutasteride as well?

Definitely make sure you aren’t deficient in any basic nutrients! I would add microneedling with the minox and see how you do before switching to dut.
