Hello, I am a 29 year old lady.I got dengue last year in july, it was pretty chronic and took almost 3 months for me to recover. I started having excessive hair faill after 3 months of dengue, and it lasted for about two months and now my hair has really become thin and its volume is less,Last month again I started having hair fall, I got my tests for ferritin, vitamin D, thyroid,haemoglobin, all results are normal. Infact ferritin level is 52,which is good enough.Last week I went to see s dermatologist, she asked me to get trichogram test, the result was that 30%of hair plucked was club hair, so she asked me to use hair 4 u solution (2%) for about 3-4 months. I am just worried about the side effects of this medication, that if I stop it, the hair fall will start again.Please suggest.
