Found hairs on my coat

Just had to write quickly about this. I know my hair length, texture and color. I found 3 strands of hairs: one thin blond hair, one curly red hair, and one short thick white hair stuck on the back of my gray wool pea coat. I'm fairly certain they came from the seats on BART because that's the only time/place I wear a thick coat-- to work in the mornings. Time to hit the dry cleaners.
