Oh, so lovely. I agree with all the other commenters here - you captured that fear of change/reluctance to let go of one's identifier so well. For some reason, I love Harry as a barber. I don't think I've read him in that particular role in fic before, but in a strange way, it really suits him -- he was so collected and reassuring and just what Severus needed (of course!). I also loved Harry's line about it being hard to avoid your hair getting shorter when going in for a cut. Haha.
