You can also try Anveya hair growth vitalizer which can help with new hair growth and this can strengthen the follicles and reduce hair fall. The best part is the product is free from chemicals.

You are lacking proteing in your diet and also hair fall could be due to hormonal changes, dust pollution, water changes. You can take a well balanced diet and hydrate your self well. Over a period of time things will be better
