Split ends or trichoptilosis results from compromised health of the cuticle due to exposure to any form of mechanical or environmental damage. Reasons could be many – from flat ironing your hair, to over-washing them, to undergoing chemical treatments, to exposure to harsh weather conditions, to using chemical-laden products, and even brushing your hair while detangling them!

Since the ends are the oldest part of the hair strands, they have been far more exposed to damaging conditions than any other part of your hair. And hence, they are much more frail and fragile.
