Charmion, I've had sink strainers in my kitchen & bathroom since the 80s when a long haired friend reported the verdict of the plumber who cleaned out their pipes. Mother & two daughters all had waist length hair - very coarse hair - & he had never seen such a blockage!

On another matter - in later years I had waist length, but mine is very fine & when it was finally cut off in 2017 - 70cm - the cancer wigs company didn't want it, they only used thick coarse hair. They would have loved my friend's hair when she finally got it cut after her physio said it was affecting her arthritis. I had a craft friend who made porcelain dolls & she was happy to accept my hair!
