I think a woman should be able to wear her hair anyway she likes. I have very thick, curly hair, and I've been waging a lifelong battle against it. I've had it very long, very short, and everything in-between. I have more brushes and implements of torture than any salon, and it's been every colour from dark chestnut ( my natural colour) to white blond (my new natural colour!). I currently have it longish, just past the shoulders, and although it is a pain to dry, at least I can whip it all up into a clip. I occasionally leave it to dry naturally, when it triples in volume, but mainly give it a wavy blow dry. I have to admit that I find long hair more feminine, which is good at a time in my life when it is easy to feel old and unattractive.
I think Mary Beard is amazing!
