The hairfall is more especially when I m applying oil n after shampooing ma hair! And I had typhoid three months which made ma hairfall even worse: can u suggest me a remedy for this?  <response>: Hello, Severe hair fall post typhoid is known as halogen effluvium wherein the hair gets transformed from growing phase managed phase to shedding phase halogen phase. This would recover gradually over 4- 6 months. I suggest you take an oral biotin supplement once a day for a few months. Hope I have answered your query. Let me know if I can assist you further.
