What months do you see the most growth after an FUE hair transplant?

It can take 6 to 12 months after surgery to see results.  If you are concerned it is best to contact your doctor

At 5 months it is likely that you only have 50% of the final aesthetic result. Therefore, I would recommend that you wait for another 7 months to assess whether you need further intervention. 

Patients see different results at different timing. Although most patients should see some result by month 5 at times it may take 8, 10 or even more to see the result. 

Usually hair starts to grow out around 3-4 months, but most of hair growth usually happens between 6-9 months. It may take up to a year to have full hair growth. 

At 5 months post-op about half of the transplanted hairs has started to grow. The hairs will initially thicken up as the process continues and the results will be noticeable. After 8 months, roughly 80% of the hairs will be growing in, and the results will be even more noticeable with a very close visual of what the final result will look like.

At a year you have probably 95% of the growth that can be expected. If this growth does not meet your expectation, then go back to your doctor and discuss this. Most of the grafts will havea broken through by the 5-6th month.
