Thinning Hair After 1200 Graft Transplant and Minoxidil/Finasteride Use

So a bit of back story, I received a small non invasive hair transplant of 1,200 grafts in temples in November 2023, 2 month prior I started 1mg of fin, and topical min. All was going well was patient with the process. By September 2024 id say my hair peaked, thick than it ever had been and less hair fall. But by January 2024 it seemed to had thinned out a bit, I know from reading this forum that you can get multiple sheds so I stayed committed and just waited it out. But now it seems I haven’t regained the ground and my hair is definitely a lot thinner all over the top of my scalp and even some of my hair has changed texture and has gone straight (my hair is quite wavy) and my hair is a lot more difficult to style. Anyone had this before or shed any light on my situation

(I do have a derm appointment booked)
