Hair loss after face and neck lift, blepharoplasty, and brow lift. Can surgery be causing this? Hair transplant done in 2019

I had a SMAS facelift, necklift, upper/lower blepheroplasty & browlift three weeks ago and am now losing a great deal of hair from the front of my scalp and crown. I had a hair transplant a few years ago (2019) and am worried this is permanent. If I just tug on my hair in these areas, I am left with chuncks of very thin hairs. Is this temporary and how how long will it continue? Is there anything I can do?
