Hair

Bob no longer wants to go to the Barber that has cut his hair for the last 10 years. So now I cut his hair and also seem to have to trim his beard etc... I cut his hair a few days ago and yesterday he looked at himself in the mirror and said. I think I'll dye my hair black, I have too much gray.. What do I use for that?... as he is rummaging in the medicine cabinet
