What is the maximum number of FUT/FUE operations one person can have in a lifetime? (Photos)

Also, can Finasteride and other medical treatments be stopped after “surgeries? 4 years after my 3rd FUT, I gradually reduced my Propecia intake and I stopped doing laser comb treatment, I noticed some hair thinning so I decided to do a final transplant. When doctors decided that “it’s enough”. Just checking for more opinions. Thanks.
