Compulsive hair pullingDefinition Return to top
Trichotillomania is hair loss caused by compulsive pulling and/or twisting of the hair until it breaks off. The hair may be lost in round patches or diffusely across the scalp. The effect is an uneven appearance. Other hairy areas may be plucked, such as the eyebrows, eyelashes, or body hair.Causes, incidence, and risk factors Return to top
Trichotillomania is a type of compulsive behavior and its causes are not clearly understood. Symptoms usually begin before the age of 17. It may affect as much as 4% of the population. People with this disorder will often seek the help of a dermatologist initially. Women are 4 times more likely to be affected than men.

Signs and tests Return to top
A biopsy may be done to rule out other causes, such as a scalp infection, to explain the hair loss.Treatment Return to top
No expert consensus exists, however various medications, particularly antidepressants like fluoxetine (Prozac) have been shown effective in reducing symptoms.
Expectations (prognosis) Return to top
Typically, trichotillomania is limited to younger children who tend to outgrow the behavior. For most, the hair pulling is time-limited to 12 months. Early onset (before age 6) is associated with a better prognosis.Complications Return to top
Complications usually arise when the pulled-out hair is eaten (trichophagia). This can result in intestinal obstruction or lead to malnutrition.Prevention Return to top
Early detection remains the best form of prevention since it leads to early treatment. Decreasing stress in the environment might be beneficial, as stress may increase compulsive behavior.
