Trichoptlosis, or split ends, are unraveled hair strands that have been stripped of their protective cuticle, causing the inner cortex fibers to fray. Once the damage has been caused, the hair can unravel up to an inch or more from its end, causing frizzy, unmanageable hair. Individual hairs may split into 2, 3, or even more strands, and each split may take place at a different location, giving the hair an uneven, ragged appearance.
