Trichoclasis
Trichoclasis is hair breakage that is seen as a clean fracture
across the hair fiber. It may develop secondary to hair conditions
that make hair fiber weak such as trichothiodsytrophy.
It can also be seen in normal hair where vigorous grooming stresses
the fiber to such an extent that the hair suddenly snaps and breaks
off. It is common to see some trichoclasis as a result of trichotillomania
(obsessive hair plucking). Treatment for trichoclasis involves reducing
the physical manipulation of hair and the recommendation of less
vigor in brushing or combing!
