Growing up I had stupidly-long hair. It was thick and heavy and limp and I never learned how to do anything with it except put it into a pony tail, and it gave me headaches all the time (and oh gosh was I tender-headed!) According to a friend it sometimes made me look 12 and sometimes made me look 30 (not something a teenage girl wanted to hear.)
My dad wouldn't let me cut it.
When I was 17 I was at the mall with friends and decided to get it chopped off. It was a bit longer than shoulder length, nothing radical, a bit curled up at the ends, very similar to my own mother's hairstyle--my friends said it looked amazing, my mom praised it, I felt like I was walking on air. This was 10+ years ago, but I still remember exactly how I felt as I walked into my father's office, this great big goofy grin my face, absolutely positive
he was going to take one look and be flabbergasted and do nothing but gush about pretty and normal his daughter looked.
Instead he scowled at me, yelled at me to get out and didn't speak to me for a week.
A while after that I tried out various hairstyles including some fairly short, stylish cuts. Dear ol' Dad told me there was a verse in the bible specifically saying angels didn't protect women with short hair.
Nowadays I don't care what he thinks of my head, of course; although when I was shaving my head last year I made sure to be freshly shorn before visiting his house.
