Had surgery 1 month ago, and developed extensive shock loss

I can’t tolerate finasteride or even topical finasteride. So I got a hair transplant and now found that I lost a lot of hair from shock loss within the past month. 

You were in a difficult place and I appreciate the problem. The price of shock loss vs the price of loss of your sex life. I wouldn’t give up my sex life for hair. The good news is that after the first shock loss, it is unlikely to happen a second time if you follow up with a second hair transplant down the road in the next couple of years.
