Short back and sides until I was about 13, then dead short, then at 14 I decided to grow it out. No haircuts for over a year then I kept it long until I was 17. Then shoulder-length and started dyeing it (firstly dark brown with a red patch, then jet black). Cut back to a no. 4 when I went to uni, stopped dyeing it. Then went shorter again until I was 25, when it all fell out in the space of 10 days. Within a month it was alopecia universalis and that's me for the rest of my life AFAIK. Couldn't give a shite now.
