How long after eyebrow transplants do hairs start growing?

It can take 6 to 12 months after surgery to see results.  Some may see hairs growing 3 months after the surgery.  If you are concerned it is best to contact your doctor.  

It will take months up to a year before all of the hairs start growing after an eyebrow transplant.   However, you should expect to see some growth by month six.

Typically the transplanted eyebrow hairs will start growing around 3-4 months after the surgery date. Some people a little early, other a little later. Between 6-9 months your should start to see a good idea of what it will ultimately look like but expect more mature results at 12 months.
