My forehead is swollen after 30 days of my hair transplant surgery. Is it normal? Will it affect my transplant result? (Photos)

Swelling 1 month after hair transplant is not normal, Please see your doctor urgently. You should not treat it, your doctor should. 

It would be abnormal to have swelling after one month. It would be in your interest to follow up with your doctor

Although forehead and periorbital swelling is fairly common after hair transplantation,it should resolve by 10-14 days.I would recommend a follow up with your surgeon.

To have swelling 30 days post op is not normal. Please see your hair restoration doctor for a follow up. 

Swelling at 30 days is not normal. You should go to talk to your doctor about why this may be happening. You also implied that the swelling went away, and only recently came back? If that's the case then I recommend the same anyways- talk to your doctor to see what's wrong, since that is not normal.

Swelling should resolve long before thirty days postop and should not recur.  You should follow up with you transplant surgeon and be evaluated in person.

This is not normal; and I would go back to see your doctor and see what is causing the swelling which is highly unusual

Not normal at all. See your surgeon in followup so they may see it and try to diagnose the issue and solve the problem.
