I generally keep putting off going to the hairdresser until my hair gets so long that it annoys me too much. When I was younger I had really long hair, and just occasionally cut the frayed ends off my self. Since getting it cut shorter I have realized that if I keep it below a certain length it gets much easier to manage: I used to have a real hard time and need to spend really long each morning getting the knots out of my hair. When it is shortish I can just run my brush through it and it all sorts it self out very easily.
