Since I'm no doctor, I'll give the official info:
According to M-W.com, the definition of Trichotillomania is: "an abnormal desire to pull out one's hair"
Mayo Clinic explains it in a bit more detail:
"Trichotillomania (trik-o-til-o-MAY-ne-uh) is an irresistible urge to pull out hair from your scalp, eyebrows or other areas of your body. Hair pulling from the scalp often leaves patchy bald spots, which people with trichotillomania may go to great lengths to disguise.
Hair is often associated with beauty and vitality. That's why trichotillomania — also called hair-pulling disorder, trich or pulling — can be so emotionally painful for people with the condition.
For some people, trichotillomania may be mild and generally manageable. For others, the urge to pull hair is overwhelming. Some treatment options have helped many people reduce their pulling or stop entirely."
So there you have it!
