Thank you for your query.
It is not unusual to lose hair following typhoid
infection. However the hair grow back to normal after control of infection.
You may try Trigaine but it is a shampoo and will not help in hair growth.
You need to take a good nutritious diet and, if required, supplement with essential vitamins
. If things do not work then consult a dermatologist
who may assess the scalp
and guide you accordingly.
I hope I have responded to your query to your satisfaction.
Wishing you all the best.
