fractured hairs[hair fractures]

"Fractured hairs" are broken hairs. A white dot forms, the hair breaks, and then a split forms on the remaining broken end. I have observed this process many times while removing my own split ends. A split forming higher up the shaft of the hair is not a result of any sort of breakage, but of a scale beginning to peel up and continuing until it is visible. I get some of these, too. Yesterday I removed several ends that had half a dozen such splits along the shaft over a three inch length, but with no breakage site.
