Hi
I am a female in her thirties and i have had a hair system for over 10 years. OK i agree, it is not great. Yes I don't like it and i am always aware of it (although i cannot feel it unless it physically touch it). There are more pros than cons for me as at the moment I have a lovely long hairstyle which I would not have other wise. I have suffered from hair loss since i was a teenager so I know what grief it brings. It isn't cheap and I can' really afford it but my life would dreadful without it.
For women suffering with being bald, I think it is a good option.
