Trichotillomania or more recently renamed Trichotillosis (also known as trich) is a hair pulling disorder. It is a condition where someone has the urge to pull their hair. This can also effect the eyelashes, eyebrows, beard and genital area. A person can be affected at any age but is more common in younger people and can affect both men and women.
It can be a rather complex condition and I feel it is not very often talked about by professionals because it is not very easy to treat.
It effects around 1 in 30 people and there needs to be a lot more awareness and support around it.
