I don't know about sueing, cause any cosmetic surgery is kind of a gamble, that said, if this case is within the "Standard of Care" I feel that it doesn't say much about the hair restoration business. If this was "filling in" maybe, but you can tell, and as he stated, much of it was not filling in but was created.
The HT community should re-evaluate what the standard of care is and openly hold accountable the doctors that produce these results. I guess that is what this website is for.
