1 month now after FUE can I shave or trim to Number 1 for the reception area and the donor area?

There should be no issue but it is best to check with your doctor who performed your surgery in case there are issue specific to your surgery.

For most doctors the cut off for cutting or shaving your head is a month after the surgery. So you shouldn't have any problems with trimming your hair at this point, unless your doctor instructs you otherwise.

yes, one month after FUE restoration , you can shave or trim no 1 all donor area ...for recipient area ı recommend you to wait at least 45 days 

you should ask the hair transplant surgeon who did your procedure for his/her recommendation. typically I tell my patients once all the scabs have fallen off and the areas are healed they are free to clip the hair as short as they want. 

In my practice I do not recommend my patients to shave or trim the recipient area at least a six months after the operation .  Better to contact your Doctor for his opinion .

at one month post op you can return to your normal routine including shaving your head without influencing the results.

IF all of the crusts have been off for a week, you can do what ever you wish for cutting the recipient area, no problem
