Finasteride and hair transplants, is it important to take it?

I get side effects from fin so I can’t take it. I’m 23 and thinking at 25 I’ll get a hair transplant. I was wondering if I’m required to take fin for it to work.

Finasteride protects young men (under 30) from shock loss after a hair transplant. When a young man doesn’t take it, they run a risk if significant shock loss of the native hair. Many surgeons don’t use finasteride with surgery in young men, and these men are writing or calling me all of the time about their shock loss.
