Are there any of you who have been losing a lot of hair lately?

I heard that losing more than 100 hairs a day is considered hair loss... and I lose an unusually large amount of hair. Picking up hair from the floor is quite a chore. Fortunately, I do have thick hair, but it seems to have thinned out a lot compared to the past. I even went to the hospital, but they said there wasn't a major problem, so I just got a prescription for shampoo and came back. How do people who lose a lot of hair manage it?
