I find shed hair everywhere. I have my hair up all the time, and have done for years. It didn't used to be as bad when I had a wooden floor in my bedroom (where I would detangling and style my hair) but my new room has a carpet, and my flatmate also has long hair that gets everywhere since she wears it down. The main difference though is that she doesn't know how to deal with the sheds before they start causing trouble. I'm emptying the shower mesh constantly, and our hair recently killed our vacuum cleaner. Usually I clear it out after every use, but I was away for a month, and when I got back the brush on it was blocked up and stopped moving - my flatmate had never heard of taking the hair out the Hoover-brush, and by the time I did it, the belt had already gone.
Usually in my room, I find a brush to be a better solution. I take the floor-brush to my carpet to pick up most of the hairs, then bin the hair and hoover properly.
I do hate the laundry- balls though. It seems my hair gets everywhere, especially if I wash my bedding or my jumpers.
