What is the best way to improve hair loss from Forehead Reduction? (photos)

I had surgery on September 21/2021 first I had shock loss in the front but this is starting to grow back quietly and now after 3 months later my hair started falling out more on the whole crown area. Now I am almost 6 months p/o and I still don't see much difference. I wonder if this is also a cause of hair loss that the skin can be stretched too much by the surgeon and therefore the hair loss has occurred? What is the best way to improve hair loss from forehead reduction? I’m really desperate…
