This article described a small study done with 50 people.  They used an over-the-counter antioxidant called N-acetylcysteine to assist in the treatment of trichotillomania symptoms.  There was an over 50% success rate in comparison to the 16% success rate in the group receiving the placebo. N-acetylcysteine (abbreviated NAC), is a pharmaceutical drug used mainly as a Mucolytic agent and in the management of paracetamol (acetaminophen) overdose, but it has shown to be somewhat effective in treating OCD and is undergoing clinical trials.

The article “theorizes that trichotillomania may be a kind of grooming irregularity that falls into the obsessive-compulsive family of disorders. “Some parrots pull out all their feathers,” he says. “Some mice pull out all their fur.”"

“That may explain why the antioxidant N-acetylcysteine can help prevent it. The compound is thought to work by reducing the synaptic release of a neurotransmitter called glutamate. As Grant told me, glutamate is the communication chemical that “tells the brain, ‘Do it! Do it! Do it! Do it!’ And the rest of the brain can be overwhelmed by this drive state.” Reduce glutamate and you may reduce the drive state. Previous studies have suggested the supplement may also reduce urges to use cocaine and to gamble.”

My trichotillomania symptoms had been getting worse since getting a puppy.  My stress levels have been considerably higher and I’ve been functioning on less sleep.  About 2 weeks ago Tareak and I picked up some NAC and I’ve been taking it daily.  I probably won’t notice any difference for another couple months, but hopefully it will help!
