Area of Science:

  • Veterinary Medicine
  • Animal Behavior
  • Psychology

Background:

  • Hair pulling, a behavior observed across diverse species including humans and animals, is predominantly seen in captive subjects.
  • This behavior is classified as a mental disorder in humans and a behavioral pathology in animals, often involving hair ingestion.

Purpose of the Study:

  • To explore the characteristics and potential causes of hair pulling behavior in various species.
  • To evaluate the reliability of research data from affected animals in artificial environments.

Main Methods:

  • Review of existing literature on hair pulling behavior in humans and non-human animals.
  • Analysis of behavioral patterns, including self-directed vs. partner-directed actions and aggression.

Main Results:

  • Hair pulling is associated with psychogenic distress, occurs more frequently in females, and is resistant to treatment.
  • Data from animals in artificial environments may not be scientifically reliable due to potential husbandry deficiencies and long-term stress.

Conclusions:

  • Hair pulling is a complex behavior linked to environmental stressors and distress.
  • Preventive measures focusing on husbandry improvements to reduce chronic stress are recommended to avoid the development of this behavior.
