Severe Hairfall- 26 yrs female.

I was diagnosed with dengue in Dec 2022. Since March 2023 I have been facing severe hair fall. I took follihair for 3 months and minoxidil soution as advised, which reduced my hairfall a little, and again, it went back to the initial stage once i stopped it. I took a few tests in November 2023 for hemoglobin, thiroid, b12,etc, and everything was at a normal rate and not deficient. Since the doctor felt it might help, I've been under medication(follihair, multi vitamins) for 3..4 months now. But still, I lose 120-150 strands every day and ever more on hair wash days. Again, they have prescribed me minoxidil solution. I am skeptical because I had used minoxidil twice earlier, which worsened my hair fall once I stop it. I even tried using pilgrims redensyl hair serum for a couple of months, which didnt do any good. my hair fall reduced to 150 strands from 200 once i stopped it. Please advise any alternatives or any serum that I can use to stop hairfall.
