Hairloss due to uncontrollable Urge to pull out own hair - Trichotillomania / Tricholomania

For people suffering from trichotillomania, hair pulling is more than a habit. It is rather a compulsive behavior, which the person finds very hard to stop. The cause of tricholomania is supposed to be the imbalance of chemicals in the human brain.

People with trichotillomania pull their hair out of the root. Some people can pull out handfuls of hair, which can leave bald patches on the scalp or eyebrows. Other people pull out their hair one strand at a time. Some inspect the strands after pulling them out or play with the hair after it's been pulled. About half of people with this condition also have the habit of putting the plucked hair in mouth.

The condition is rare - statistics show it affects only 1% to 3% of the population, although new research suggests that the rate of hair pulling may be around 10% or higher.
Trichotillomania affects about twice as many girls as boys. Most people who have trichotillomania develop the condition during adolescence. However, it can start when a person is as young as 1 year old.
