No universal cure yet. Some people have managed to effectively manage trich, but this is more like managing alcoholism - it is always a possibility to relapse.
There has been research in the past about different levels of dopamine or seratonin in trich sufferer's brains, but no single 'wrong gene' or chemical imbalance has been found that fits all. Until that happens, the focus is on management rather than cure.
