Severe hair loss. How can I treat this? (Photo)

I'm 23 years old. I'm having hair fall problem since 2020. But at that time it wasn't so severe. But from last year I noticed thinning in hair lines, there was continued hair loss but not as much now. From Last 2 weeks hair fall increased 10 times more. I had high fever 103 degree but only for 2 days. I got my period 15 august and since then hair started to fall severely. I'm taking biotin but my baby hairs are also falling. My TSH, CBC and RBG report is normal.
