Can washing my hair with hot water a few days after a procedure harm my grafts?

As long as the the water was not applied with direct pressure (i.e. from a shower head) then there is not likely to be graft damage from washing your hair. If you are worried about damaging your grafts, consult with your hair surgeon and follow their guidelines on haircare after surgery.In the meantime, I have supplied a link below which includes information on recipient area healing.
