Im washing hair every 3 days once, only to lose so many hairs. what I should do. is Dengue a problem ? [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Post dengue it is extremely common to face hair fall as the platelets in your body diminishes considerably. Work on your nutrition Have multivitamin tablets which especially contain biotin  Hope that helps! </s>
