Bumped my head about 3 months after FUE hair transplant. Did I do any damage to grafts? (Photos)

Bumping your head 3 months after surgery should not affect the results of your hair transplant surgery.

Nothing to worry...3 months after hair transplant all grafts take or some of them lost anyway and you can start to your normal life and do everything, including every kind of activity, smoking, close contactsports so on. 

At 3 months you have nothing to worry about. Your grafts are essentially as secure as your normal hair, so the only way to cause them permanent damage would be some seriously intense trauma, big enough that it would affect any normal hair in the same area. Mild injuries like what you have shouldn't affect anything.

Believe it or not, it is a not rare issue that the patients bump their heads after HTS as ai just mentioned at our 21st Orlando Hair Transplant Live surgery workshop. Also it happened 1-2 times after my HT surgeries. In your case, I don't see any impact in your results, just let the redness and swollen go away to continue the wound healing process of the scalp.

I would not worry at this point if you bump your head. It's during that first week (particularly in the first 5 days) that the grafts are very vulnerable to getting dislodged. After about 2 weeks following surgery, the grafts are fully in place even if you bump your head. The shaft of the grafts do shed around this time and the follicle goes into a resting/dormancy phase but begins to grow starting at around 4-6 months. 

By the 3rd months everything in your recipient area is stable and hitting it will not impact the growth at all
