Assuming that post-Covid shedding is a form of telogen effluvium (a stress reaction that can occur from a case of illness, among other things), it would start around 2-3 months after the illness, and end 2-6 months later.
I didn't experience shedding after my Covid, but my case was extremely mild (easier than almost any regular flu I've ever had). However, I've had TE from other causes. The shedding gradually increased for about a month, after which I shed heavily for around 2 months, and then again gradually decreased over a month, similarly to how it started, until it just one day stopped as if it had run into a wall.
