I'm not a woman, but I do have an aversion to paying for my hair to be cut. Particularly because I don't have a complex hairstyle.
Generally I cut it myself, every 2-3 weeks, but can occasionally persuade Emily to do it for me "*tut* not a-bloody-gain! You're always cutting your hair!"
She has had a variety of lengths and styles, from Number1 all over, to wool + plastic weave, to shaved sides with longish top, to quite naturally long, to shoulder length, to short, to aaaaaaaargh! Why won't my hair grow faster! (the current phase).
Her rule of thumb is: I shall wear my hair as I wish... unlessitwontbloodygrowquickenoughgoddamit!
