Hello!
Extreme hairfall can be due to monsoon and some nutritional deficiency.
You can get your tests done, start with multivitamins and lifestyle modifications.
Along with that you can go for PRP - 6 sessions one session monthly. It gives great results in stopping hairfall.
Recommended tests - CBC, TFT, IRON, VIT D3, Vit
B12.
After tests you can get your reports checked up and start multivitamins accordingly.
