M.T.
My daughter is 16 months old and has had her hair cut twice now and I was only charged $5 and I gave them a $2 tip. I figure when I get my hair cut I usually give a $5 tip so since her cut is not such a big deal to do I tip less. I tip a set amount no matter how much the cut cost because it is still a cut. Plus if it is a different person everytime then they are not going to know how much you tipped the last time.
