I recovered from covid but now i face a hair loss what should i take for hair fall?

Try to increase circulation to scalp by either massaging castor oil or vit E oil, avoid hot oil. Use gentle shampoo and moisturizing conditioner. Use microfiber towel to dry. Avoid hair styling products. Eating healthy meals helps more than the advertised supplements. If hair loss continues, please see a dermatologist sooner than later. Hope it helps.
