I agree with you on this 100%. I too struggle with trich on a daily basis and I was actually really offended when I saw the last picture in this article.
I fail to see the humour in the last image in this post. As a person who suffers from trichotillomania I actually find it very offensive. Uncontrollably pulling your own hair out is not funny and it is something that 1 in 25 people struggle with every day.
