Yes, our dog used to do this too but occupying with treats definitely helped. We worked together to do grooming - one of us to occupy the head with treats and warn the other when they felt a snap was likely coming. 6 months was especially hard but at the age of 2 now he doesn't really do this anymore unless we accidentally really manage to pull hair in a sensitive spot.
I'll disagree with others and say we found castration massively helped aggression problems - but I don't know that what you are experiencing is anything out of the ordinary for a lot of dogs so I don't know how relevant it is in your case. We had more serious problems with guarding resources, locations as well as fairly major body handling issues and had had bleeding puncture wounds and bad bruising. About a month after neutering the ferocity of response he was capable of diminished considerably as did the number of occasions he resorted to using aggression. We waited until 10 months to neuter.
