I cut my head on recipient area 5 weeks after FUE and there was a speck of blood, did I lose my graft? (photos)

After hair transplant we ask patients to avoid exercise for 7-10 days because once you exercise, the blood supplies goes to your muscles. We want to enough blood supply to remain in the scalp, so these grafts can survive. 

We do not recommend young patient before the age of 25 to perform a hair transplantation as the hair loss will go on and this means that you will need more surgeries in the upcoming years. Therefore you should start to use minoxidil and finasterid to prevent hair loss and maybe 2-3 years later ...

Recipient area feels numb because superficial nerves get damaged during the hair transplant by any of the technique. These usually recover by 3-4 months. 

We recommend our patients to start 20 days after the surgery with Rogaine  5% (Minoxidil) foam spray twice a day but this can change due to your own surgeons recommendation. Please consult with your surgeon about his/her after care recommendations.

Hiccups are rare but they don't last more than a day or two.  There is no specific drug to treat hiccups.

It is great to see you have realistic goals and expectations.  You can think about the density this way:  2000 grafts were place in an area that probably had about 20,000 hairs.  With your hair cut so short it would not look very full.
