I have had AFiB for about 13 years and I am 79 years old and had very thick curly hair until 2020 when I got Covid then a few months after that my hair started to fall out and my curly hair was straight and hard to comb. It quit falling out about a year later then I got Covid again in Jan of 2024 and now my hair is falling out again and is very thin. I do not know how many Covid longhaulers have had this happen.
