Hypothetically can Finasteride for shock loss be discontinued after a period of time has elapsed after the Hair Transplant operation and the risk of shock loss has receded?
Yes, you can take finasteride temporarily to just protect against shock hair loss. I generally tell patients to take it for 8 or so months to bridge the gap between the transplant procedure and growth from the new grafts.
But if one wants hair bad enough to have surgery, it would be wise to take a drug that can stop/reverse hair loss.
