Heavy hair fall two months after typhoid. Will it grow back?

This sounds like telogen effluvium — temporary hair shedding that starts 2–3 months after an illness, high fever or stress. The good news is that it usually recovers on its own within 3–6 months. Eat enough protein, iron-rich foods and be gentle with your hair. If shedding continues beyond 6 months or you see bald patches, consult a dermatologist to check iron, vitamin D and thyroid levels.
