So, you’re rocking the sexiest hairstyle – it’s all working, it’s bouncy, it’s shiny – but your ends are a frayed, hot mess. The truth? Nothing ruins good hair like split ends. And unlike most hair issues, almost everyone has them, regardless of hair type – because the causes are so universal. Splitting is a direct result of stressing out your strands, and who isn’t guilty of doing that? If you over-process (think relaxers, perms, and color), use too much heat-styling, brush it while wet, handle it too roughly, or go crazy with the sun-and-chlorine exposure, your ends are over. Scientifically speaking, each hair fiber is enclosed by a layer protecting it from damage – the cuticle. But when the cuticle is damaged, it’s no longer able to contain the elements that hold the fiber together, resulting in splitting.
