How Much Weight Do You Need to Lose Rapidly to Trigger Shock Hair Loss? Can It Recover?

I weighed around 85-86kg before this, and now, two weeks and two days later from the initial depression episode starting, ended two days ago, I weigh around 80-81kg apparently according to the scales. I am concerned, thats alot of weight to lose in such a short time. It is different with different people, but 15 pounds per months could trigger hair loss with the genes for balding on board.
