DON'T HASSLE HER ABOUT HER SPLIT ENDS AND THE NEED TO COME TO THE HAIRDRESSER MORE OFTEN!
It doesn't make her want to go to get her hair cut because she has to be all apologetic and feels the pressure to give substantial reasons for her slackness. So she puts it off and off and then it gets worse so then the hair looks worse.
However, this woman finally decided that things were desperate enough that she'd crawl back and get a haircut.
Not the favourite thing to do - time-consuming (what is with that head massage? - just rinse out the conditioner already), inane chit-chat, getting a half burnt head by an apprentice blow drying the hair, and then the trauma of having to sit in front of the mirror that shows the rapidly ageing face in all it's glory.
Hair does look nice though.
