Hello dear. Please understand that about 80-100 hairs shed normally everyday. That should not be a problem. However, if you feel that you are losing more than that, then you will need proper treatment.
Previous illnesses (2-4 months ago), certain medicines, synthetic colours etc can cause hairfall called telogen effluvium which is transient and self limiting.
Next Steps
Eat a high protein diet. Schedule an online consultation for further assistance
Health Tips
Avoid using shampoos with SLS. Avoid artificial colours and fancy hair treatments at local parlour
