The biggest in the world, measured by a combination of factors - primarily by their scale and marketing reach but also factoring in the number of people who say they had SMP at that particular company, as well as a good dose of prior (well informed) knowledge. There are three clear leaders, and a number of smaller (but still significant) clinics. If you disagree with my assessment, I have no proof to offer other than my word, but I can assure you I am absolutely correct.
I did not mention names, because no doubt I would have been accused of being a shill or something. There is no need to explain the concept of SEO to me, it's what I do.
I know this industry very well indeed, however I do not wish to compromise my position by elaborating on this point. Like yourself, I have a strong interest in the process and the industry as a whole, and I believe there is a bright future for those companies that do it the right way.
For the record, micropigmentation qualifications mean virtually nothing in the world of SMP. Some of the worst results ever seen were performed by qualified micropigmentation 'experts' using 'high quality' machines, needles and pigments, yet these people preach about the importance of qualifications and the need for regulation. That's the real sham.
Put the right equipment and the right inks in the hands of a skilled artist with the RIGHT KIND of experience, and you'll get the best results, regardless of how many pieces of paper with their name on they may or may not have.
I agree with some of your points, but not with others. Unfortunately I do not get breaks at work, so I don't have a great deal of time to post here. You speak like someone who has more to do with this industry than you're letting on. That's fine, because so do I. Just because people don't show their entire hand doesn't make their views any less valid. I respect your opinion and wish you well.
