To answer your question, why would I consider it when I know they are overpriced?:
Essentially because that they say it is permanent solution, that is well maintained (through their appointments), undetectable and natural, like having your own hair.
To be honest, if they could deliver on these promises I would be happy to pay a premium over a standard toupee supplier. But unfortunately this does not seem to be the case.
Thanks for your feedback toddy.
