Hello and welcome to healthcaremagic I would keep a possibility of Telogen Effluvium. Telogen is the resting phase of hair growth cycle. After any stressful event e.g medical illness like dengue, typhoid, jaundice etc the hair gets shifted from the growth phase (Anagen) to resting phase (Telogen) which is manifested as increased shedding. Telogen usually begin 3 months after the stressful event and can last up to 6 months following which the hair follicle re-enters the growing phase. I would suggest a good, healthy, wholesome diet, rich in nutrients, vitamins etc. A daily oral Biotin supplement would also help in aiding in faster recovery. regards
