Yes, several months after having a bad case of Covid, over 50% of my hair shed out. Thankfully, I have thick hair; so, I still had hair left all over my head. It did grow back. However, several months ago, my hair started shedding again. It’s called telogen effluvium. I am wondering if this will be a permanent cycle? My hairdresser said this happens with people who have had the vaccine as well.
