The message has always been clear: if you have split ends, cut them off. Yet, 50% of people in the UK pick at split ends on a daily basis, 80% of whom are women. Known medically as, trichotillomania, this habit can lead to more problems than simply having a bad hair day. When you pick and pull a strand of hair in two, you cause irreversible damage to the length of the hair shaft. In most cases, this will lead to your hair eventually breaking off, resulting in uneven, thin ends. In severe cases, a split end that is picked and splits all the way to your scalp, can result in follicular damage. We asked Hersheson Stylist, Jordan Garrett, about the ramifications of this naughty habit.
