Last night I bumped my head and blood came out. Have I lost hair graft? What should I do? 1 month post op HT. (photos)

If the injury was severe enough to cause normal hair loss then it may affect your transplanted hairs.  Bleeding may be a sign that you dislodged a graft(s).

If you did not hit it very hard there shouldn’t be a permanent damage. The critical time to cause permanent damage is mostly the first week after the HT operation. 

: You have terrible crusting which should have come off from good washing techniques after the surgery, An FUE is treated just like a regular hair transplant with regard to the recipient area, but the donor area has open wounds which require daily washing with soap and water. An FUE is treated just like a regular hair transplant with regard to the recipient area, but the donor area has open wounds which require daily washing with soap and water. Within 3 days of surgery, you can resume full activities, heavy exercises if you wish. The recipient area requires daily washes as well to keep the recipient area free of crusts. I generally recommend the use of a sponge and supply my patient with a surgical sponge to fill with soapy water and press on the recipient area daily. By repeating this daily, all crusts can be washed off without any fear of losing grafts. IF any crust is present, use a Q tip and dip it into soapy water, and roll it on the crusts and that will lift them off without dislodging them, but never rub them, just roll the Q tip on the recipient crust. I like to see no evidence of any crusting in the recipient area and the crusts from the donor area gone in 3-4 days with daily washing. To get the crusting off, you need to leave the shampoo on your hair for 10 minutes and as the crust become water logged, then will come off with gentle finger action. Repeat this twice a day until it is all gone. The crusting you have will, if bumped, cause bleeding and possibly graft loss

If you bumped your head hard enough to damage the follicles then the ahir may not grow. But if you didnt damage the follicles then the hair will grow out.
