I'm suffering from intense hairfall from the past two weeks. This started when I went for swimming for straight 3 days. I had put on swimming cap and took bath immediately after swimming. But my hair got frizzy and dry and there has been massive hairfall since then. I also had dengue 3 months back. Now my hair has become so week even applying a mild pressure pulls out 2-3 hairs from the roots. I have applied egges and curd on hair but it did not solved the hairfall problem. Is this a condition telogen effluvium that usually occurs post dengue? How long is it supposed to last? Should I do some blood test? Which blood test? What precautions should I be taking? Thanks in advance.
