My ds has a diagnosis of HFA and has been tugging and twiddling with his hair for a few months now. Today we visited GP who says he has trichotillmania. I asked the GP what can we do to help him and his reply was there is nothing we can do, he just has to resist the urge. So i was wondering if any of you know of anything we can do to help him, does anyone have any experience of trichotillomania.
