Bumped and cut my head 2 months post FUE hair transplant - will this affect new hair growth or kill grafts? (photo)

Hello. Loss of grafts at this stage is extremely unlikely especially as it appears to be a superficial laceration. 

If the injury was severe enough to harm your non-transplanted hair follicles, then it may be a problem.  If you are concerned, it is best to follow up with your doctor.

Hello, Dr. George Abrahamian here from LA FUE Hair Clinic in Pasadena, CA. Trauma to the head at any point after a hair transplant isn't great, but the closer you are to your transplant day, the higher the likelihood of long term issues with the grafted hair. Typically, trauma within 10 days after hair restoration may lead to long term loss of the grafted hair, but not always. Trauma two months after restoration more than likely will not cause any issues to the either the natural hair, or the transplanted hair, and if it does, its likely to be transient, and not a long term issue, based on the photo you have shared. However, if the trauma is so severe that it tears through multiple layers of skin, and requires stitching, those hair follicles (transplanted and non transplanted) may not recover if there is dense scar tissue formation. If it was a slight bump that maybe bled a little bit due to superficial skin trauma, and did not require stitching, you should be fine! I hope this helps.

It doesn’t take as long as 2 months to heal the FUE so that means that it doesn’t damage the surgery if it happened after 2 months and getting in touch with the surgeon if you experience any pain is a good idea.

By two months, the grafts have healed in and should be as durable as native hair follicles.  A bump should not cause any problems unless it was sever enough to damage your native follicles- from your description and the photos this is not likely.

At this stage the hair is as resilient as normal hair. So only an injury that is serious enough to kill normal hair would be enough to kill your transplanted hair. You are probably safe, but only an in-person examination would enable a doctor to confirm.

at 2 months, it is likely that you did not do damage to your grafts and full healing has occurred by this time
