How many people have trichotillomania?

very very many people including me , most people who have trich think they are alone but they are not.... I have trich! its really embarassing.

In the US alone, it is estimated that 4-10 million people have trichotillomania. This number is hard to estimate however because so many people with this disorder choose to keep it a secret. It is considered a "rare" disorder but in truth it's only rare because it isn't well known to both people who have it and people who don't have it.
