I'm 14 days post FUE. Dead hair follicles after FUE procedure?

You cannot tell if a hair follicle is "dead" by just looking at your scalp.  It will take 6 to 12 months to see your final results. 

Two Weeks is just not long enough. It is a tough waiting game to see the results. But as long as the surgeon did the best he could with your available donor, you will get a result.

There is no initial way to determine of your grafts have survived the hair transplant surgery. If you had an experienced and surgical team I would not worry. You will know the answer in 6 months
