Would you say Finasteride is required for a transplant to be successful?

No, Finasteride will not help the grafts grow. Finasteride works to accomplish two objectives:

(1) slows or stops the balding process or

(2) prevents shock loss in men under 50 who have a hair transplant.

The likeliness of shock loss for men decreases with age. It is worse for men in their 20s and less so in their 30s and so on.
