Sometimes Ted just doesn't listen to a woman
I was watching the Tenessa episode today. She had medium length hair that was wavy and she told Ted her one requirement for her haircut was that it be low maintenance. She didn't want to have to blow dry it or straighten it out, with two small kids she didn't have the time.
So what does Ted do, he gives her a haircut and takes it up shorter, and then blow dries it straight and even flat irons it in places. Why didn't he show her how to style the haircut with her natural waves? Why show her a style that is the exact opposite of what she asked for?
She loved the cut and style, and it did look good on her, but you know she'll never wear it that way in her everday life.
