I have been measuring one dry lock of hair at my forehead (I have layers and each hair on my head is approximately the same length right now). I don't have a tape measure but when it is dry and I pull it straight, it is the length of my comb plus the width of one finger, with a few sparse hairs sticking out further than that. And my hair sits in the nook of my collarbone if I pull it around to the front. ah, measuring without a tape measure! I will report back in a month and see if I have any progress.
