Why are these short hair stubbles not growing after FUE 10 months ago? (Photo)

After 10 months, you should begin to see some hair growth. If you are concerned please follow up with your doctor for an exam.

Thank you for your question. Keep in mind that it takes time for your existing hair to fall out and for the regrowth cycle to occur. Many patients require up to six sessions, along with two maintenance treatments, for the best results. Always work with a board certified facial plastic surgeon.
Best wishes,

Hi!
This could be ingrown hair after FUE. After being pulled out the chances are it will grow back normally
All the best!

More than likely those are the hair shafts from the grafted hair that just didn't fall out yet.  What you can do is allow them to fall out naturally, or just wash your hair more to help them fall off easily.  I wouldn't recommend you pull them as they could be hair that is still dormant and will eventually grow out.

No,  they  do not fall out naturally with new hair growth.  Actually  those are death  follicular unit's hair shafts and should better to pull them out with tweezers.

Good Evening and thank you for your question, These hair stubble mostly are no longer connected to a live follicle and can be plugged out. They may not fall off naturally, but it is absolutely okay to pull out this hair stubble when you know its around 10 months post undergoing the procedure and ideally if the follicle had to grow new hair, by now it should already have. 
Regards

This stubble should have come out by now. You should also have most of your hair grown. These stubble reflects some of the old hair shafts that remain and can be pulled out
