Hello, Welcome to HealthcareMagic forum. Typhoid or enteric fever is an infection which affects many organ systems of our body like gastrointestinal , liver , skin etc . Hair loss after typhoid is common and sometimes may be severe enough to cause extreme thinning , breakage and bald patches. It is a known effect, though it s not permanent, one cannot predetermine the exact prognosis in each case. Many patients regrow the hair normally after few months to a year . But since you are young and this is causing much anxiety to you it s advisable that you consult a dermatologist for confirmation and appropriate diagnosis. Also a multivitamin supplement daily along with plenty of water and a healthy lifestyle will help you recover the lost health & vitality. Hope this answers your query. Regards
