Hello dear! Any severe illness, causes severe stress, the main cause for hair loss. As your online doctor, I advice you: First, to truly believe that all the hair will come back, and get fine, which means to stop worrying Second, to take a food supplement, the one which is full of vitamines and has the highest dose of biotin Third, to take pure virgin coconut oil, one teaspoon per day orally, and half teaspoon spread it on your scalp and leave it as long as possible, after that wash your hair with a baby shampoo - three times per week Forth, be patient, it will take 3-6 months for your hair to completely recover think positive, you will be fine!
