I have FUT surgery scheduled in late late December. I am planning on taking propecia in Mid-November..so is this long enough to prevent shock loss. I do not want to go through this shock loss that others have reported.
The longer the better, but 4-6 weeks should cover you. Even a shorter period will work, but taking it is critical particularly if this is your first hair transplant and you are under 30 years old. Shock loss is most common in young men and after the first hair transplant. Stay on the medications until all of the results are achieved and then consider staying on the drug for life. Talk with your doctor about this.
