Hair loss in young age is very distressing. In your case, the first hair fall
(the one that happened immediately after typhoid
) looks like telogen effluvium
to me. However, your current hair fall may be unrelated to that event. More often, it is male pattern baldness
unmasked by telogen effluvium.
Please visit a qualified specialist and get evaluated. Simple bed side tests like hair count, hair pull and photo trichogram can give you the diagnosis. Some blood tests may be advised to rule out rare causes of hair loss.
As a future doctor, I am sure you realise the importance of diagnosis before treatment. Feel free to ask further if you have more queries.
