Final answer:
Over-grooming and self-mutilation are psychological behaviors that can manifest in hair pulling or self-harm. Seek professional help for treatment.
Step-by-step explanation:
Over-grooming and self-mutilation are psychological behaviors that can be observed in various contexts, such as body image disorders or mental health conditions. One example is trichotillomania, a condition where individuals have irresistible urges to pull out their own hair. This behavior can lead to hair loss and dermatitis. Another example is self-harm, where individuals intentionally injure themselves as a coping mechanism. It is important for individuals experiencing these behaviors to seek professional help for appropriate treatment.
