I did grow to below-butt length after a campaign to see how long it would get.
But it got too hard to take care of, for me, so I cut it in half.
But I'm posting to give hope to those who want long and think their hair doesn't grow because I had NO IDEA mine grew past BSL. But when I just Did Not Cut It it got a whole lot longer. This was about 6 years from a bob. I don't think I'll grow this long again, maybe if it all goes gray, because I'd like to have a looooong thick gray braid.
